In class topic

In my sociology class we talked about "Tearooms" and someone said "If they go in there for gay sex and it's a bathroom, why do they call it a tearoom?" everyone was silent and then I said "Well, think about it, there is an act called Teabagging that is a sexual term." The group stared at me. "why is it called tea bagging?" asked the person from before. everyone muttered in agreement. I sighed as I knew nothing of any of it, but put it together by seeing those troll player videos. "Think about it, You dunk a tea bag in repeated to get the flavor, And in the sex act they...." I started to say but got interrupted by an outcry of disgust. That said, the least experience person in the room knowing the most about a subject is funny.
