Input: Text: this actually happened a really long time ago but i just remembered it now.

my old grammar school had a small cafeteria and couldnt fit all the students all at once so the teachers would ask some of the 8th graders to look after one of the lower grades while the they could take their lunch breaks. this was a weekly thing and during that week, it was my turn, along with my friends, to look after the second grade class.

this is were the fuck up begins.... me and my friend were just joking around and eating our lunch when one of us, i forgot who, says "butt pirate" for no apparent reason. apparently, one of the youngsters sitting near us heard it and started to spread it around the entire class. 

a few minutes pass and there was still time me and my group of friends decide to play a game of charades since everyone was done eating and there was still time before recess. my friend who i was goofing around with earlier decides to go first. he's doing his thing and the first guess goes up and like the impressionable rugrats that they were, they start yelling out butt pirate. they all start yelling butt pirate and calling each other butt pirates. we all tried to stop it but it was too late, the age of the butt pirates had begun.
