BA

A vulgar term for a person who defies authority; the rebel doesn't care about breaking rules and does what he/she wants without thinking about the consequences; or it could be a guy on a motorcycle that beats people up.

Those who think you're being a wuss or weenie may use BA to stand for b**** a**. (Yes, that's the closest we can come to typing out BA's actual meaning on this clean website. If it helps, b**** a** rhymes with ditch lass.)

Confusingly, this meaning of BA is the exact opposite of b** a**. (Rhymes with mad lass.) So, BA itself can be either a compliment or an insult, depending on the context in which it is used. If the message that includes BA is insulting and/or derogatory, BA likely stands for b**** a**.
