Break the Dam

When under the influence of alchohol, breaking the dam is the first urination of the night, where after the liquid inside you flows constantly and leads to you constantly urinating throughout the binge.

Oh man, im gonna have to go break the dam.

Break the damn

When you have to hold in explosive diarrhea and you finally can relieve yourself.

I ate too many spicy buffalo wings last night, I couldn't wait till I got to work so I could break the damn!
