It is mostly filled with unattractive ADHD women, stench-ridden males who are most likely stoners or complete social outcasts (who ironically are hated by most of the club). You have the exceptions like the few actually attractive girls but they are all traps because they are all lesbian (well the High School version of Lesbian) or the guy who seems perfectly fine but when you befriend him it turns out he's ready to commit suicide at any moment. Mostly because he fell for one of the traps.
Contrary to popular belief, people who fall into this clique do fall into relationships. But all of them are extremely creepy or clingy, none of these relationships end well for either side.
The Anime Club will never fall far from each other. Once you join, there's no getting out. You ARE going to become one of those people mentioned above. It's a HORRIBLE decision. If you do join, prepare for massive amounts of Pocky begging, Hetalia jokes, over-the-top High School Drama, ugly disturbing nerd sex, voice-actor worshiping and the surprisingly little amount of ACTUALLY talking about anime.
Guy 2: "That's the anime club group."
Guy 1: "They sure seem completely obnoxious."
Guy 2: "Don't get me started, I know what it's like to be in there."
Guy 1: "How'd you get out?"
Guy 2: "... I didn't."
