Tandem Urination

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! Let’s try out tandem urination!

Tandem grave

Used to swear on something serious, showing you’re not lying, not playing, and speaking with full truth or intensity. Similar to saying “on God,” “on my life,” or “on bro nem.”

“Shorty badder in real life than IG, on tandem grave.”
