A sexual act occuring in or near a toilet bowl. The male party of the sexual couple does the female in a standing dog directly above the toilet bowl. When he is about to ejaculate he shoves the female's head into the toilet bowl, flushes the toilet, and then ejaculates on the unsuspecting, toilet-flushed face of the female.
This is when a person becomes a hindrance on any type of group activity or event by raising concerns and not going along with the crowd.
Why is Greg such a Terd in the punch bowl. I know he ruins every party by telling his stories of how donkeys are great companions, we keep telling him chicks don't want to hear about donkeys. After reading the secret that guy has been a real drag.
