A fetish performed during anal sex in which the "receiver" gets any clump of hair on their body sucked and chewed vigorously with each thrust. This is done repeatedly and completely randomly back and forth between partners. Also may involve quoting of classic cartoons such as Jestons, Flintstones, Yogi bear, etc.
Guy1: Dude...do you chack?
Guy2: Hell yeah!! OH MAN you shoulda seen me chackin' last night! I was on fire man. I swear I must've had five pounds of hair between my teeth.
Guy1: Aw no way, man! I was chacking this morning. I had her screaming things from the Smurfs.
