While in midair (from a jump for example) you fart on your hand and slap the fuck out of someone next to you (generally the back of the head or the face.)
Jarome: "Can you believe it, that bitch didn't want to deepthroat me?"
Tim: "What did you do about it?"
Jarome: "I kept giving her Uncle Grubby's Specials until she did what I said."
Time: "Yeah thats what I would have done too."

A big fat greasy ass kid, commonly in his early teens, who has a tendency to physically exert his sexual desires aswell as put his hand in his pants during public situations. There is a large chance that a 'grubby boy' is a future nonce. If you know any grubby boys, DM me cause I want them (no homo)
