Yeah, sure, fine. I'll start.
For those wondering, the "GEEK Club" (spelled in caps) was little more than an excuse for the chemistry teachers to circlejerk about Doctor Who with the students who were fans of the show. But, since that doesn't sound good to the school board, it was turned into an all-around "nerd subculture" group. How it worked was, the club had full access to an entire hall of rooms, with each room having a different "activity". Movies and TV, Games, Tabletop RPGs, and Books. Now, guess which one was the first to close? If you guessed books, you'd be correct. Nobody there had actually read anything, it was all regurgitated Tumblr and Reddit nonsense. Movies and TV was so they could constantly play Doctor Who, and "Tabletop RPGs" was just for GURPS and Munchkin. Also they sold snacks, because reasons.
Now, the main event, and the reason why 90% of the people in the club attended, was the Gaming room. Most of the time it was Smash Bros, but one day it was mixed up and someone brought an NES. Most of the people there didn't know what an NES was and wanted to play Call of Duty instead. Ended up playing Zelda. Fun stuff.
Anyway, they tried to force group activities once in a while. The most prevalent one was the "costume party". I went as Mike Hammer, which no one recognized. Oglooger went as a personification of Nazi Germany. Or Italy, one of the two, and won third place because people thought it was Hetalia. In any case, the reason it sticks out for me is how many Homestuck cosplayers were there. My God, I had no idea how infected my high school was before that point. I was just in awe of all the autism in the room. I eventually decided to get away from it all and just play Rock Band. I was the only one that liked Rock, so I ended up being made to play terrible pop nonsense.
Fun times.
