It is a fusion of a boob job and a jerk off. It's when a girl is masturbating you while your dick is between her tits and she's sucking your dick at the same time. Also when you see a girl with a lot of tits you that's a boob off case.
Last night a girl gave me a boob off it was amazing
This girl has huge tits that's a boob off case
A contest that is held between two women with breasts of similar size and shape that is
usually instigated by male onlookers. The contest is to determine who has the larger and/or
better looking breasts. This contest is to be held with the contestants topless.
Dude, that chick has some hot tits. No dude, that other chick has some hotter tits.
I disagree, looks like we need to have a boob off.
