after being a part of several rps where this has happened, I have determined that having jerky characters and douche bags is usually asking for someone to get pissed at your character and then you for making him or her, it keeps happening and then arguments break out which ruin the experience.

Depends on the character. I've had good characters who were complete and utter jerks, but no-one had a problem with them oocly. It all depends on the readers ability to realize it's just a character. Take for example a char in one of my Roleplays named Loretta. She's literally an evil maniacal bitch and everybody knows it. Everybody hates her, even I hate her. Doesn't mean me and the other players can't get along :P

Though I can see where you're coming at. It needs to be done right, if someones being a jerk for the sake of being a jerk and constantly in your characters face it can get a bit irritating.
