Input: Text: so, this happened many years ago now, when i was about 15/16. i was generally a quiet kid in school and though i had a good sense of humour, it was generally only with my close friends. 

so, one day i'm sitting in class waiting for the teacher to turn up and was chatting with one of the, shall we say, slower members of the class. cue the fu. 

i can't remember the context, but i ended up making a joke/reference to glory holes. however, the girl had no idea what one was and began pressing me for details. naturally, i shied way from answering, so she loudly asks the rest of the class what one is. 

turns out i was the only one in that room who know what a glory hole was. the entire class began questioning amongst each other and all calling out to me to explain what one was. this was too much attention for my introverted self to handle, but it only got worse. 

my teacher entered the room and was immediately bombarded with questions about what a glory hole was, to which she claimed ignorance, and the questions were redirected back at me now by the teacher too. 

i was forced to awkwardly explain to my teacher and my entire class what a glory hole was. all for one off-hand remark to a loud girl. now i look like some weird creep in front of all my peers. 

one of my more embarrassing moments, for sure.

TIFU by introducing my entire class to the concept of glory holes.
