aggressive avoidance

The act of not being in the same place as another person (i.e. avoiding, ghosting) in such a ridiculous manner to blatantly demonstrate that the absence is not circumstantial, but a deliberate choice.

Aggressive avoidance involves tactics that often appear to harm the doer more than the receiver. However, the avoider's self-inflicted pain or inconvenience is offset by the thrill he/she gets from blowing the other person off.

Janet: Does your roommate still live here? I haven't seen her in the hallway for the past few weeks and her car isn't here.
Tiffany: Oh, she still lives here. Look at her scaling side of the apartment building to get into her window. Her aggressive avoidance is because she lost a fight with me. Silly bitch.
