Input: Text: hello reddit. excuse me if there's any grammatically incorrect sentences here, my fingers are really shaky and it's hard to think straight. i freak out really easily wow.   

okay, so i'm on my school group. there's 49 students on it. i meet them nearly everyday. i've never sent anything on it, nor am i social irl. i'm the guy that sits in a corner doodling, avoiding social contact.  

anyway, today, i decided to break my virtual silence. the topic of conversation was one of our dickhead teachers, who happens to be a muslim. a dude cracked a mildly offensive muslim joke and i don't know why, it made the light bulb in my head shine bright. you see, i'm the guy that loves dark humour, and i often spend hours on /r/imgoingtohellforthis and on 4chan, so i have a wide array of offensive jokes. i think 'fuck i gotta send this shit to them. they'll think i'm hilarious!', forgetting that there's stupid religious people in my class who quite obviously won't find it funny.  

anyway, i post this (http://imgur.com/4mfljjq). it doesn't exactly settle well... i start freaking out. i still am freaked out. there's a guy who thinks this joke is racist? huh... normally, i'd call him a foolish mango; seeing how islam is a religion, not a race, but at that moment i felt strangely apologetic. basically, i just went batshit crazy in my irrational freak out period and apologised for something that i wouldn't usually apologise. everyone thinks i'm even weirder now. great. i'm contemplating on being a professional hermit now. i definitely have social anxiety.

TIFU by joking about Islamic buttsex.
