When having heated sexual intercourse in the cowgirl position the male performes the "marsh" by grasping the back of the females head and bucking forcefully with his hips until the females head enters or pierces the headboard/wall behind.

Marsh is the most intelligent and prettiest girl in the world. She’s very lovable who will dazzle everyone around her. Not only is she clever, but she’s also good at art, music and sports!!!! Most importantly, she even bakes. People always compare her with the Disney princesses, in which people thought such impeccable human being only exists in fairy tales, not until they met Marsh.

A character from a show called South Park, her first appearance is in "An Elephant Makes Love to a Pig" season 1 episode 5. She is known for being Stan Marsh's sister. Shelley is 13 years old in the recent seasons. She has braces and messy brown hair. She's very rude to her brother. She is also the best character to ever exist.
Me: "Do you know who Shelley Marsh is?"
You: "Oh Shelly Marsh? From South Park yeah!! "
Me: "it's Shelley... Not Shelly... "

Similar to Swamp Trash, but from a slightly different variation of wetland, commonly found in England especially. Marsh Trash differ from their Western cousins in that they have an even more difficult to understand dialect often referred to as "Br't'sh" but find joy in many of the same past times, such as settler colonialism, racism, transphobia and other types of bigotry.
