First Pee 

The very first time you wake up in the middle of the night to pee.

I'll take my contacts out at first pee.

Race To Pee First 

When 2, or more people have a race, and run to the bathroom (for example: at least 2 males, at least 2 females, or at least a male, and a female if only 2) to see who will pee in the bathroom first if there is particularly 1 bathroom where they are.

Scott, and I would race to pee first in the bathroom to see who would pee first.

Fist in the stink, pee in the sink 

While your fist is inside someone's rectum, you pee in the sink simultaneously.
