koo

a person who is a total genius. These people have GPAs of 5.1. Even though there is a lack of koo-i-ness in people, they totally own any other random last names. Comes with a huge abnormally large head. Common sense not included.

Wow did you see how that smart guy walked into a wall and then crushed it with his abnormally large head, must be a koo.

Koo

Originally the result of a mancunian attempting to mimic a seagull, the word 'Koo' is best used when stoned to warn others around you that you are in said condition. It can also be used as a substitute to just about any other word in the english language, though such usage is ill-advised as it can irrevocably damage your social life and lose you some serious pulling opportunities.

1:Basil: "Kooooooooooo im fuckin well stoned"
Trevor "Koooooooo me tooooo"

2:Gary: "Are you kooing then you koo-faced koo-dodger for koo's sake?"

Ahmed: "Koo off"
