look up any word, like fleek:
A word with no particular definition. If you don't know quite what you'd like to say, simply in sert it with a 'gwaa'. Great for when you're in an environment where curising isn't allowed, or when you want to get out of explaining something in detail to someone.
What the gwaa?! Why is he with her?

I really want to gwaa tonight.

Boy: Hey, why didn't you call me last night?
Girl: Uhh...I had to do laundry and cook and gwaa...
Boy: Oh ok!
