- noun
The act of expectorating recently ejaculated semen into the face of the jizzum donor. The expectorate must be expelled in such a manner so as to be well distributed over the recipient's visage, so as to simulate or suggest the shrapnel damage that so often accompanies concussive chemical experiences. Note that a primary blast area or concentration of impact is not uncommon.
