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.

Mouthwashing

The act of ignoring or playing down the severity of a situation, specifically in relation to abuse of people or abuse of power.

The term comes from indie horror game of the same name in which all of the events that occur are a direct result of inaction when abuse comes to light.

Mouthwash, as a product, is inherently useless when used by itself, as it is only capable of temporarily masking the smell of poor oral hygiene and not maintaining proper hygiene or fixing the cause of the smell.
Jimmy wouldn't do that, he's my friend! He's never been violent towards me!
Dude, just because a guy is your friend doesn't make him a good guy. You don't know what he does when he's not with you.

Come on, maybe she's lying to get sympathy.

Dude, do you hear yourself? You're mouthwashing right now...
I'm not I just...
Really gets rid of that bad taste, huh?
