A maneuver made in hot tubs by creepy men. Involves using legs as "pinschers" to trap the legs of unsuspecting girls. Recommended if you want to seem like a total rapist.
Stefaun: Ooh that girl is lookin' fine. I'd like to crableg the shit out of her!
Everyone else: No, Stefaun... Crablegging is completely socially unacceptable.
