The correct and contemporary term for all religions\cults.
"Did you hear about Jeff? He lost his mind and joined a church."
"A church? You mean one of those Imaginary Friend Clubs!!!"
A person posting impossibly stupid inflammatory comments with the goal of many innocent people being forced to degrade this person publicly in their replies. This is a higher degree than a basic troll.
Did you see Tanya posting this comment? "Really, how did slaves build the United States of America? Do tell. The north didn't have slaves and their economy was industrial. No slaves." Yeah bro, Tanya is a total Insult Slut! She gets off on innocent strangers telling her how stupid she is.
