A "Cheese Grater" is someone of incredibly low inteligence. The term Cheese Grater comes from the belief that all inteligent people start with a base I.Q. Like cheese (you start with so much), and these imbeciles come along and shred every precious point from you; simmilarly to how one grates a cheese block.

Depending of hetero or homo sexual, having the sex partner suck your dick while gently sliding his or her teeth up and down your cock.
After the prom you and your girlfriend are trying to do work. To get hard your girl not only sucks your dick but slides her teeth up and down your dick putting pressure on the dick making it hard as rock. If your girlfriend does this, she is giving you the Cheese Grater.

Similar to a "beandip", but for skinny or regular sized people.
After many years of taking thousands of beandip's to the manboob from his skinny friend Dylan, Gino finally took revenge against him by scooping Dillon's nipple with his hand and then shouting "Cheese Grater!!!"
