upon finishing the activity of an "upper decker" (shitting in the upper tank of someones toilet) you then dump an entire bottle of dishwashing soap in the tank and then flush the tiolet so the bowl fills up with bubbling shit water....
Tom pulled an upper decker on Bills shitter, and I finished it off making it a root beer float!

A girl can't make up her mind who she wants to sleep with. She decides to bring both guys home, one black and one white. They have a 3-some with the white guy on top and the black on the bottom.
She couldn't decide so ended up getting root beer floated.

is a type of sexual play that occurs when one partner has diahrea, either naturally or threw means of enema, and shits in a glass. Then the male partner is arroused to the point of ejaculation and creates a nice foamy topping of jism. Afterwards either partner drinks it.

When someone bends over, ass up in the air. You spread there ass hole open and piss directly into it. The shit and piss froth up, giving it the appearance of a Rootbeer Float.
