A “par” breaches social and common courtesy, eg, a disrespectful comment could be seen as a “par.”

“Par” can also be used as a verb, eg, “You just got parred.”

This slang term could be a British abbreviation of the French “faux pas,” meaning an embarrassing or tactless remark in a social situation.

“I don’t mean this as a par, but did you remember to wash this morning?”
