When a mom finds out about a high school party, calls all of the parents who had children involved in the party, and then tells the parents their children are horrible people. This results in the situation being blown out of proportion and everyone feeling resentment for the mother who acts according to the above description.
"Wow, did you get in trouble too?"
"Yeah, but it is all because my mom is Pulling A Linda."
"Your mom is a horrible person."
