The point when you have become so close with someone that you want to share every moment, even taking a piss. The woman sits on the toilet spread eagle, and the man urinates between her thighs. Also, a great hobby for couples stuck in a rut.
Him: Babe, gotta pee!
Her: Me too! Letâs try out tandem urination!
The crunchy goodness that remains on your genitalia after a long night of making love.
You know itâs been a good night when you roll over to say good morning and she notices the fuck crust.
