cut block

When a chick's friend comes over and takes her attention away from you spitting game. Not necessarily a cock block because there's no guarantee at that point you'd fuck, but her friend is cut blocking you from making progress.

So I was talking to her in the kitchen, and then her stupid friend came over and cut block me and took her outside to talk.

rock block

The notice of an engagement ring when sizing up a potential mate.

I saw this hottie the other day at Starbucks talking on her cellphone. She smiled at me and I thought to myself, "Game on!" That was until I approached the bar and saw the band on her cellhand. Total rock block!

Ken Block It

Term originated from Ken Block's gymkhana videos. Currently this term is used to target anyone with an AWD vehicle, especially a Subaru, to skillfully maneuver their cars around, over, and through a series of concrete, dirt, metal, human, tree-like and other obstacles using underdog acceleration and braking of their cars in comparison to Ken Block's STi.

Person1: Nice WRX you got there. Did you Ken Block it yet?
Person2: Word. Pulling off stunts and drifting this thing the day I got it.
