What does "boo" mean?

This one guy and I have been flirting back and forth (nothing too serious) and recently in one of his text message he's said "hey boo". The thing is, he has a girlfriend. Does "boo" mean girlfriend or just like sweetie?

  • There's wifey, baby, and boo in that order wifey is the top notch where all girls want to be. Then there's baby that's ok he likes you have feelings for you but not better than wifey, than there's boo not really nothing he can call a lot of girls that even girls at the super market... but boo means sweetie in other words'' boo is just easy to say and text... and esp when he has a gf..
