taco block

Like a cock block, but perpetrated by a female.

I was eyeballing a cute guy at that party last Thursday but I got taco blocked by that girl with the curly hair before I could make my move.

cum block

Similar to a cock block, this is the act of walking in someone (usually a male friend) while they are having sex, to stop them from making it all the way.

Guy 1: "I was rooting this chick the other night, I was about to blow but my mate walked in and totally cum blocked me."

Guy 2: "Tough luck man."

cop block

I was super tanked at this rager and was about to hook up with this bangin' blondie but then I got totally cop blocked.
