Good ones posted already, more than once.
Here's one, roleplayers who are drama "arsonists". They log on every night with a new completely dramatic situation that demands everyone's attention RIGHT NOW, over and over again. Until nothing is going on except whatever tragedy is going on with that person in that given moment. They put their character in life threatening danger over and over again to remain the "star of the show". First night it's a broken arm, next they started a fight that nearly got them killed, a third they're in trouble for stealing the Sultana's nightcap and need you to break them out, and so on and so forth.
Another, roleplayers I call "appropriaters". They never noticed how interesting a certain part of the lore could be in roleplay until they see you using it for your character. Suddenly they're incorporating the same thing into their own character, except there's is way more better than yours at it. They don't just interpret the will of elementals, elementals follow them around and chat about the weather with them, or intervene to protect them from harm, leaving something you've been roleplaying a year as an insignificant footnote.
I guess my "pet peeve" can be summed up as selfish people who role play.
