A Root Beer Float is when poop and jizz are mixed. First recognized as a teen when one had to hide themselves in the bathroom to masturbate. One would sit on the toilet with a dump in the water, proceed to masturbate and turn around to jizz on to the poop in the toilet. This creates a mixture of brown and white that looks similar to everybody's favorite cold treat, a root beer float.
Poop, poop, poop, poop, poop, poop, poop, and jizz, that's what a motha fuckin root beer float is!
