look up any word, like blumpkin:
(Pronounced: coo-goo-goo-sloo)The shortened version of the insult "Cum Guzzling Gutter Slut". Usually put in this form for gamers, skaters, and just those who are just too damn lazy to say the entire thing. Only to be used in the most extreme of situations and cases of severe peer humiliation and must be used skillfully lest the speaker makes himself look like an ass.
