A sentence enhancer used by inept speakers to infer that we actually "know" what they intend to say. Commonly used in 2 circumstances: 1) Speaker has no clue what he/she is talking about. 2) Speaker is blond or has the last name Kennedy.

Equates to: "You really don't know but I wish you did."

Is a term that is used to replace words you dont want to say.

telling someone that they know something

1. Said after explaining something. You are telling them they know

2. Said after cracking a joke. You are telling them that they know that it is funny.

3. Said randomly at a random time, just to sound hella gangsta or leet

Said in a sharp low voice at first, and then released out the mouth at a progressively higher pitch (but still maintaining a deep voice). Like this: YOOOUUUU KNOOOWWWW!!!!!

This can be used when talking to friends about drinking in company that you do not want to hear that you are drinking. e.g. when your at school or with your parents
