Notch

A notch is a line of the eyebrow missing. How it occurs: a person claims that they will or could achieve something ludicrous. Notch is then called and if the action isn’t completed the person who stated the claim receives a notch.

Owen: I could have a threesome tonight if I wanted.

Matt: Notch

Owen: Fuck, there’s no way I find two girls. I guess I deserve a notch.
