cockblockbuster

A high-grossing hollywood film that is so emotionally disturbing that it eradicates all sexual desire for hours, or even days.

Dude 1: Didn't you guys watch Schindler's List last night?
Dude 2: Fuck no, man! That cockblockbuster turned Jenny celibate for two weeks last time she saw it.

cockblocker

One who prevents a guy from banging a girl. Usually a friend or family member, motivated either by jealousy or the fact that they can't get any and don't want to see you get some.

I put the moves on Jane last night but her protective cockblocker brother aggressively cockblocked me and asked me to leave the party as he didn't want me to get any.

Clockblocked

In basketball when you make a shot off the shot clock and it doesn't count or having a made shot called off because of not getting the shot off in time.

I thought I hit the game winning shot as time expired but I was clockblocked by the buzzer.
