1. n. the human mouth. You want me to punch you in the wazoo? Shut your damn wazoo!
2. n. the stomach or belly. His great wazoo hung poised, out over his belt, like it might dive down to the floor and bounce off across the room. Pow, right in the wazoo!
3. n. the anus; the buttocks. (Jocular and euphemistic.) One more word like that and I’ll give you a kick in the wazoo that you’ll remember for a long time. She fell so down! Right on her skinny bazoo.
