Generally a gay man's acronym which simply stands for Broke And No Trade. In other words a gay man with no money and a small penis.
After visiting a man's home and having a romp you realize that the person doesn't have a nice house and car, no visible signs of success/money and nothing impressive between the legs. Next time you see him with when you're with your friends you mention "I hung with him the other night and found out he was BANT, so stay away!"
