Diarrhea butt stuff. When the fecal matter is runny and is in enough liquid to give it the color of iced tea.
Man, I was doing anal with my girlfriend, and I look down, and there's runny shit all over my dick... I mean I still finished and stuff. Turns out I'm into iced tea on the back porch.
When you fuck the ice tea and somebody drinks it.
Damn jimmy just got some of my ice tea surprise
