v. To reach around from behind someone (particularly a woman, but may be a man) and grasp their breasts. Usually done without prior warning.

Comes from the shape of one's hands when grasping said breasts -- fingers looking like a crab's legs -- and the breasts themselves -- being the fruit.
I was minding my own business one day while walking down the street and some pervert crabfruited me! Needless to say, I wrecked his balls.
