glowball

A sexual performance that includes a black light, some highligthers, and any sexual acts that result in the explosion of semen onto the ballsack which then glows due to the blacklight.

That slut Sharon is a wild one; she glowballed Drew all night long. Now his balls will never stop glowing.
