one of the most commonly misconstrued sayings, an example used in Boondock Saints "a man is allowed to beat his wife with a stick no thicker than his thumb." A claim made by a satirical caricaturist by the name of James Gillray against a judge. The first and original use of the saying is as simple as the words. The thumb was used as a readily available tool of measuring. Such as the Tailor's rule of thumb "the circumference of the thumb twice, is the circumference of the wrist, twice the circumference of the wrist is the circumference of the neck, and then twice the circumference of the neck is the waist's circumference." Then there is the Brewer's rule of thumb where if the temperature of the wort wasn't insufferable by the thumb it was cool enough to pitch the yeast. It has now been used as a term of commonplace knowledge in a field.

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.
I don't know if Beto is ugly or just a potato thumb.
There's nothing worse than a potato thumb trying to hit on me at the club.
Why is your potato thumb ass still talking?

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.
