The tendency to dislike or disapprove of someone’s actions, regardless of their nature, once they’ve been widely deemed an "asshole" by others and their inconsiderate behavior has solidified your personal dislike for them. Even when you recognize that you engage in similar behavior—behavior that isn't inherently rude or malicious—you’ll still feel disproportionate annoyance or anger toward their actions.
"I know I can be a bit loud in public sometimes, but when Sonya raises her voice like that, it triggers my asshole bias—I just can't stand her doing it, even though it's something I’ve done myself."
"I’ll admit, I sometimes text during movies, but when Mark does it, it drives me crazy. His constant texting just sets off my asshole bias"
