The act of dressing up as a crumpet. Covering yourself with butter and jam and then through a series of dance like shaking movements attempting to remove them before your competitors.
Man that was the worst crumping I have ever seen, you were as fresh as just out of the packet.
a sexual position in which a man squats down as if to hop(like a frog) and the woman then grabs the manstesticles from behind clamping them between her fists, tugs up and down and eats out the mans asshole.
"come on and finish your beerhoney, im going to give you a frog clamping like your granny never did,YEEHAW!!"
worst dancing in the world. made from the new gen. hip-pop and needs no skill what so ever to do.
crumper: man im hiphop
bboy: man your hippop
crumper: ohh yea i am hippop, i know nothing of hipHOP and its orgins, thanks man
bboy: no problem you suck anyways
