1. and batty mod. crazy. You are driving me batty! You are bats if you think I would ever wear a haircut like that.
2. and batty mod. alcohol intoxicated; confused and drunk. The guy was bats—stewed to his ears. He was a bit batty, but he’d been drinking since noon, so no one was surprised.
3. and the bats n. the delirium tremens. (Always with the.) My buddy is shaking because of a slight case of the bats.
