Mucus, Moist, Slimy, etc. <- These make me uncomfortable.
Lol, Nub, kys, bruv, bb, and using a lot of the internet slang in a sentence," Lmao I'm k, wby bb?" Annoys me.
I also dislike when people unironically do this: " I found 'me' stuff". I had a 'fake friend' that would always say, "What do you think of me [Insert an object, that she has and I don't, here] "(She did this a lot). So when people use 'me' in that way, it just naturally annoys me... It's okay if someone uses it sometimes.
