instabust

Upon seeing a chick so hot, you instantaneously cream your pants. It's like a super-fast wet dream, but awake and in public. Often used in hyperbole since guys don't actually do this, except lame-ass premies.

Guy: Dude, did you see how tight that chick's ass was?

Guy 2: Yeah man. I just instabusted.

*As you pass a hot girl*

Dude: Instabust!

When something so good happens you cant help but creaming your pants instantly.

Man when Sean Dockery hit that 3 as time expired over VT, the whole stadium instabusted!
