ass-thumbing

Ass-thumbing is when you go to the bar and drink Captain and ginger, and then you strategically place your yourself between 2 people and nonchalantly stick your thumb in someone's butt. The goal is not to get caught and to make the person getting ass-thumbed think it was someone else. Ass-thumbing also goes by " doing the Crosby" Ass- thumbing is believed to be a German tradition, and in the States, there is an ass-thumbing group in the mid coast Maine area.

Potato Thumb

A potato thumb is a person you can't decipher whether they look like a potato or a thumb. Someone who's very existence annoys you, because you just cant put you finger (or thumb) on what object they most resemble. You can't be friends or date a potato thumb without the constant need to address the resemblance making them completely undesirable.
