look up any word, like blumpkin:
 
20.
A deposit of cum that seeps out of a condom that has mistakenly slipped off your dick during sex and is subsequently left inside your chick's vagina after you nut and pull out. The fuse is lit as soon as you realize that when you pulled your prick out, the dirty rubber was no longer attached (usually because the chick squeezed it off in ecstasy or you went soft). Exhibits an unfortunately long fuse, lasting anywhere from less than a week to a full 28 days or, if the bomb is armed, 9 months, at which time the bomb drops and your life as a partying slutting beer guzzling college faking frat boy/girl comes to an abrupt end. Next time keep your prick hard and grab the rubber before you cum. Or just do it in the ass.
Dude #1: "Bro I saw you walking home with (e.g. Monica) last night man, she was soooo drunk. You hit that shit nasty?"
Dude #2: "Man, yeah, but no fucking joke. I dropped a time bomb in her."
Dude #1: (solemnly) "Shit. Shit man. Shit."
Dude #2: "Yeah, shit. I knew I should have put it in her ass."

1.
Term describing a rolled blunt/joint stuck through weed into the hole of a packed bowl so as you eventually get to the bottom of your blunt/joint you ignite the bowl. The word is used more fittingly when the bowl is packed with keif or bud of higher quality than in the blunt/joint.
Me: "Man, how are we going to accentuate this smoking session, it's new years for goodness sake!''

Friend: "Timebomb bro"

Me: "What?"

Friend: "Stick this fatty through that trainwreck bowl, smoke it down, bomb goes off."

Me: "Oh cool"

*fumbles around trying*

Friend: "THREAD THE NEEDLE NIGGA THREAD THE GODDAMNED NEEDLE!"
