back teeth are floating

When somebody has to pee so bad that the urine has filled their whole body all the way up to the back of the mouth and makes the back teeth float in urine

I had to piss so bad that my back teeth are floating

my back teeth are floating

Rude form of, “I need to urinate.”

A man is talking to another and states, “ oh wait a minute, my back teeth are floating.” Then walks off and urinates.
