Acronym for Big Gay Tom. When a bachelor gets engaged and can no longer pull chicks out of dive bars because he is in a 'real' relationship now, he is officially a BGT. When a drinkin buddy goes BGT he is no longer a wingman.
We were at chilly palmers bar but my buddy wouldn't take the fat friend because he is BGT now. She wants to hook up, you going to take her home or you going to be BGT tonight?
