Weehuu is basically the same as n00b, newbie or nab, so a different word for a rookie. I don't know where this word started, but probably by a retard. So, if you ever see a player or some one saying weehuu, they are talking to a beginner.
Oh man! That dude was way more weehuu than you are!
Stfu weehuu!
Weehuu, you suck ass!
