graveyard for knuckle children 

Nickname given to the bedroom of a male in his mid-20s who still lives with his parents and is hopelessly single, ergo, masturbates frequently. There is an audible crunching sound upon entry, reminiscent of the scene in "Indiana Jones and the Temple of Doom" when Indy and his Lady Friend discover a secret passageway and proceed to walk through it in darkness to the sound of insects being unknowingly crushed beneath their feet.

Scene: Dustin's room, aka "graveyard for knuckle children" - When the police turned on the black light it was clear that this was ground zero; for after all, it was a graveyard for knuckle children.

Suckle On My Knuckle

Something you say in an argument; meaning the person you are arguing with is not an intellectual and is genuinely not smart. When said, (depending on how weak they are) it will either kill you or turn you into a vegetable. For someone to defend against these powerful words, you must be of the highest grade of intellectual and practice the religion of Shreklenomly. People who practice in this religion are made immortal.

Pete: U is a dummy
You (the superior): Suckle On My Knuckle
Pete: *dies*
