The Mouthwasher 

The mouthwasher is an allegorical maneuver exercised by sexual narcissistic males over degenerate and profligate skanks. Such poetic act occurs when the female attempts to suck the male's genitalia but is rudely interrupted by the latter, as he orders her to firstly rinse her mouth with mouthwash - somewhere in the lines of: "Look at me. Do you think I found my penis on the streets? Go rinse your mouth you fucking whore!"

John: Guess who just fucked who?
Peter: Whom did you fuck this time John, you son of a gun!
John: I fucked Iris John. Yeah Iris the skank!
Peter: Broooo!!!!
John: And you know what?? I maneuvered the mouthwasher!
Peter: Brooooo!!!!!
John: I violently pushed her whore-face away from my penis and..
Peter: Brooooooooooooo!!!!
John: and I told her go mouthwash your mouth you whore!!! and I kicked her outa the bed.
Peter: BROOOOOOOOOOOOOOOOO!!!!!!!!!
John: Yeah. She went rinsing her mouth and came crawling back
Peter: Respect

rhodesian mouthwash

A Rhodesian Mouthwash is a sexual act when someone either shits on the floor and deposits the shit into their partner's mouth, or directly shits into their mouth. Next, they cum into their partner's mouth and make them thoroughly chew the semen-shit mixture. Their partner can either swallow the substance or spit it back out, like mouthwash.

Man, that girl over there needs a hearty Rhodesian Mouthwash.
