Used to describe a situation or a person that is not cool. Three Dubs stands for three W's (dubs), which go into wiggity wiggity whack, hence three dubs. Not only is it whack, it is superbly whack.
1. Me not getting my own way is so three dubs.
2. That girl over there is three dubs.
3. Do not hang around someone who is three dubs.
