Graceland Gerni
You invite a girl around to your place. You put on some Elvis music. Take off her clothes and get her on all fours. Take a huge dump on her back then before it dries, power piss that shit off like a “gerni” high pressure cleaner
I shit on my girls back and had to power piss it off it off like a gerni to get her clean. We were listening to some Elvis tunes at the time hence the “Graceland gerni”
