Montanan Mouthwash 

When the female partner in a relationship puts her discharge in a shot glass and the male partner puts his own dingleberries in the same shot glass as the discharge, they both lick the shot glass clean simultaneously without swallowing or spitting the combination of the discharge and the dingleberries. The partner who has licked up the least amount must swish and gargle the mixture in their mouth, even the rest of the concoction licked up from the winners mouth.

Hey babe I'm feeling playful and competitive lets do a montanan Mouthwash
