A derogatory term for Orientals. They look like they're always squinting. Possible reasons for evolutionary development include squinting to see they're tiny penises and breasts. And when the Japanese bombed Pearl Harbor, they were flying eastward into the sun, so their eyes directly contributed to the deaths of 1400 Americans.

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!
Guy 2: Yeah man. I just instabusted.
