I kind of want to know if this happens to people, well obviously, but i do cringy stuffs on a daily.
My top one is that i used to run Naruto-style and unfriended someone just because they moved from the Naruto fandom to Yugi-Oh dandom. Boi i will never forget.
Also recently i pretend like i'm a bot on Lineplay and when someone requested a friend request or give me hearts i'd go like "Fufufu~ Thankyou for the heart. I never knew i was so popular~"
