Outlawed in so e jurisdictions, a Jamaican Mudslide occurs when a male is engaging in doggy style intercourse with a partner. The male makes sounds as if he's going to blow a load, but instead turns around and sneakily defecates on the partners back, mimicking the feeling of a warm load. The partner usually notices what has happened only when it is too late, and feces is already sliding down your back (hence: mudslide). Usually, the increased weight of the feces or smell of the room alerts the partner to second guess what is on their back. The discovery is generally unfortunate.
Sarah: What happened to that guy you met on Tinder?
Judy: We were having sex and he said he was going to bust on my back and I said ok. I then heard weird sounds and felt a very heavy, warm spot on my back. I stood up quickly, and his poop slid down my back. I was very embarrassed.
Sarah: Tinder is nuts. You got a Jamaican Mudslide.
