Thumb Promise

A Thumb Promise is a promise stronger than a pinky promise. It shall never be broken, and if so, then the person who broke it may never be trusted again. Crossing your fingers does not invalidate a thumb promise.

“She thumb promised me she’d get me a drink if i called mom upstairs for her.”
