The act of a male and a female having intercourse until the male is almost at climax, where the male then pours multiple bottles of different coloured food colouring dye into his urethra before continuing. At the point of climax, the male fills the female with his semem mixed with the food colouring dye, which gives off the appearance of a rainbow.
"Elyalesiana was feeling pretty down, so I gave her a rainbow stream. She seemed to be fine after that."
"Dude, I fucked up."
"How, dude?"
"I gave my chick a rainbow stream on an unsafe day. Now I might end up with a rainbow-coloured baby."

The act of a man urinating into a woman's mouth while she urinates onto another partner. The partner may urinate however he or she likes to give it a better effect. Ideally the top man will be standing. The middle person will be on their knees or squatting. And the bottom partner will be laying on their back, with their mouth open under the middle partners genitals.
Kelly, Clark & son had a family fun night. They decided to partake in an Ohio fountain stream. Clark pissed in Kelly's mouth, while Kelly pissed in son's mouth. Son just pissed on himself, (With a boner.)
