To shower a girl in loads of cum, preferably on the face but the tits will do nicely as well.
There's nothing better than seeing a hot, big-titted girl get cumblasted.

A Cum-Blast is usually considered a single shot of ejaculate emitted while busting a nut. A nut-busting may consist of several cum-blasts.
My cum-blast sent a monsterous wad of cum straight into her eye!
