When a male lies in a bathtub, filled with water, or sometimes soda, and a female sitts on his face, farting, causing the water directly over his face to bubble. Following this, the male turns the female over and jizzes onto her face, giving her a creamy topping.
"Get me six cases of publix soda and meet me in the bathrooms with no cloths on...tonight im giving you a root beerfloat"
To pull out right before you are about to cum as you are fucking someone's ass, then sticking your dick in their mouth and cumming. the person gets a root beer float if they had a dirty asshole.
This guy I picked up last night had a dirty asshole, so I gave him a rootbeer float.
