An acronym for Part-
time Asshole. Someone who is generally a good human being, but outspoken in their defence of infringements of common decency or moderation. They will go on the attack (metaphorically) online and in real life to defend their friends, family, animals and even strangers. They speak out and
fight against
human ills such as discrimination, oppression, cruelty, trolling etc.
Matt: Aren't you going to delete Ash's comments from your post? They're outrageous!
Helen: Nah, it's

mean to me and Ash is a great
guy and only a PTA.
