In real life id say friend drama, some it is just so stupid. I've dealt with a lot of it this year and now i dont even wanna talk to any of my friends cuz its so ridiculous you know?
As for on the internet i'd say oc/rpg drama. sure you have those ocs that are better than others, sure. but to give people death threats or make hate groups just because you think your above them. its so over the top
Auuuuuuuugh they're all bad!!!! If I had to rate them all, I'd say friend drama first, then Art theft drama, then OC drama, and then the dumb fandom dramas, and I'd put family drama last, cause my family's okay when it comes to drama... ^^
