Paste, (v). to shoot viscous white fluid onto someone, i.e. come or semen. Used as a common San Jose CA slang in the 80s. Most popular on the south side on Union and Cambriana near two rival high schools, Pine Hill (where the special needs kids went) and Valley Christian (where the rich yuppies' kids went).
(v). to beat up, or pretend to be beaten up, by or from a fellow student at the bus stop near the rival schools, or any school really.
(v). To pretend to have super powers that allow you to shoot the paste from your fingers, not your penis, followed by slushing noises. Usually if you do this you will be considered a moron or deranged.
