pb blast
An act of masturbation involving peanut butter. Pb blasting with chunky peanut butter started with gay men who wanted that authentic feeling of being inside another mans asshole without the smell of feces, but eventually everyone began substituting sex with different kinds of peanut butter to satisfy their fantasies.
Fuck you then Carl! I’m going to get some skippy and do a pb blast if you don’t wash your asshole!
