You are the badass hero. You are about to detonate a bomb that will kill you, destroy the enemy and save humanity. What is your last badass quote?

What the fuck did you just fucking say about me, you little bitch? I'll have you know I graduated top of my class in the Navy Seals, and I've been involved in numerous secret raids on Al-Quaeda, and I have over 300 confirmed kills. I am trained in gorilla warfare and I'm the top sniper in the entire US armed forces. You are nothing to me but just another target. I will wipe you the fuck out with precision the likes of which has never been seen before on this Earth, mark my fucking words. You think you can get away with saying that shit to me over the Internet? Think again, fucker. As we speak I am contacting my secret network of spies across the USA and your IP is being traced right now so you better prepare for the storm, maggot. The storm that wipes out the pathetic little thing you call your life. You're fucking dead, kid. I can be anywhere, anytime, and I can kill you in over seven hundred ways, and that's just with my bare hands. Not only am I extensively trained in unarmed combat, but I have access to the entire arsenal of the United States Marine Corps and I will use it to its full extent to wipe your miserable ass off the face of the continent, you little shit. If only you could have known what unholy retribution your little "clever" comment was about to bring down upon you, maybe you would have held your fucking tongue. But you couldn't, you didn't, and now you're paying the price, you goddamn idiot. I will shit fury all over you and you will drown in it. You're fucking dead, kiddo.
- The trick is to press the button just as you start talking. With good timing, you can get stuck in the speaking animation long enough to make it through the fadeout and cutscene. Your character should then emerge unscathed on the other side of the barrier.
- This world does not deserve me. Be better kids.
- It's guerrilla, not gorilla.

"What does THIS button do?"
- My first thought too.

Bomb voyage.
- Monsieur Incroyable!
- This is it.

Smoke me a kipper, I'll be back for breakfast
- What a guy.
- Stoke me a clipper, I'll be back for christmas
  
  Stroke me a flipper, I'll be back for Hanukkah.
- Was looking for this one

- I will always upvote Waterworld.
  
  I honestly don't understand how there isn't some kind of Waterworld... either action/fps mmo, ala destiny or warframe... or just some kind of mount and blade type single player game, or even Conan Exiles.
  The closest thing I can even think of is Raft - Stranded Deep.
  ... Its mad max... on the ocean, and is basically postapoc/dieselpunk.
  Bang wow zoom, fairly novel game (by modern standards) for a AAA or even AA studio to try.
  
  "Paper! Lookitit! SMELL it! PAAAAAPER!"

I would get nervous, fuck it up. Then try to save it; making it more cringe. Then detonate the bomb just to end the awkwardness.
- "Remember me as... as a guy... but like a really humble guy.... because even though what I'm doing is great and makes me better than you... I am not...."
  
  explodes into orange juice
- ... Sorry, you failed your perception check as well.
  As you pull out the 'bomb'...
  You are startled to discover it is actually two ramen noodle packs, each of which has slightly torn packaging, out of which a bit of crumbled dehydrated noodle bits leak.

So long, and thanks for all the fish!
- Along those lines, I was thinking "Oh no, not again."

With my last breath, I curse zoidberg!
- My only regret, is that I had Boneitis
- Nice one.

It had to be me. Someone else might have gotten it wrong.
- I wasn't expecting to be sad in this thread but there it is. "I am the very model of a scientist Salarian..."

"As a language model, I'm unable to produce a badass quote."
- I'll be back

- Yippie kayak, other buckets
  
  Nine-nine!!

LEEEEEEEROOOOOOOOOOOOOYYYY JEEEEEEEENKIIIIIIIIIIIIIIIIINNNNNNNNSSSSSSSSSSS!

Whistle "Pop Goes The Weasel".
- Hell yeah, classy! Especially if you hit the button on that last up note.
- Lot of great options here, but this is the most badass by far!

I’ve hidden a treasure somewhere on this planet.
- You want my treasure? You can have it!
  
  I left everything gathered in one place.

Big Bada Boom

I. HATE. SAUERKRAUT!
- Guess that's all I'm really tryin' to say...

- What is this from?
  
  I Think You Should Leave

Don’t close my tabs, they’re all important

"OOOH! What does this button dooo!?"
If I have a companion, they are obligated to shout "DEEDEE, NOOOOO!"
My name isn't Deedee, but those who get it will get it.
If that isn't acceptable, then watch Space Ghost: Coast to Coast, pick a random quote that you feel is appropriate, and just go with it!
Otherwise, "OXFORD COMMAS FOR LIFE!"

"Damn. This is gonna be the coolest thing I've ever done, and I'm not gonna get to see it."
alternately, go classical if you can summon up the appropriate amount of rage... "To the last I grapple with thee! From hell’s heart I stab at thee, for hate’s sake I spit my last breath at thee!"
- Depending on the tone, say it in your best Matt Berry voice

"When you see the devil, tell him who sent ya."
- "Hey, that guy said to tell you-"
  "I heard him."

Bake 'em away toys.
- What’d you say, Chief?
  
  ... Do what the kid says.

Smoke me a kipper, I'll be back for breakfast!
- Unfortunately BlameThePeacock beat you to it.
  
  Woozle wuzzle?

"Pull my finger."

Don’t touch my stuff when I’m gone. It’s booby-trapped!
- Alternative:
  "Destroy my hard drives"

Fuck. Now I will never know how that book ends

There shall be light.

Somebody set up us the bomb!

Oh crap, I should've thought of a cool quote before pressing the but

There's no way I'd waste that moment on something serious.
"Skibidi", which would be funny because I'm not that young.
- Your enemy is justified in retrospect.
  
  You're just jealous of by sick dabs and mewing-sculpted jawline. /s

With a gentle half-smile: Honestly? It was a blast.

I'm off to... Bombay!
Dies in a particularly violent unceremonious explosion*

BONZAI!
Would work best if we're in an aircraft and there's a tiny plant nearby, though.

CHICKEN JOCKEY
- Flint and steel!

Sphynx of black quartz, JUDGE MY VOW!

"Pizza's done"
It isn't like the enemy is going to be alive to ponder whatever I say and whoever recounts the tale will make up something more memorable anyway.

This will really hurt tommorrow, I guess.

Be sure to drink your ovaltine

Death is light as a feather
Duty heavy as a mountain
- Alright Lan

"I-...fuck me, I had something ready for thi--"

Something to do with precious bodily fluids
- Purity of blessed fluids

Okay, I know this is a really bad idea but I'm already here so Here we fucking go... RAWR!!
