1. To be cooler than cool. Coobs has worked its way into internet chat slang. Used mainly in MSN conversations and mmorpg chats, this word is a hip twist on a combination of the words cool and boobs, which elevates its meaning above plain old cool.
The most common use for coobs stems from talking to your friends on msn. They may say something that you don't really feel like responding to, and that's when you type "coobs". They'll be like, "sweet, he was listening", when you really weren't.
