A bully telling a nerd exactly what is going to happen when they see each other.
The nerd dreading it but at least they know what to expect.

You'd always been careful to schedule dnd when your roommate would be gone

By the end of the night all your players were wedgied and dumsptered.
And from now on, you were her plaything.
