When the fatter upper puss area, also known as the "fupa", is filled with oozing, yellow juices (jizz). The pressure inside the fupa becomes so great and erotic that the jizz has to "cum". The fupa juice is expelled from the large twat/cooter in a blast-like manner. This is known as a fupa blaster, commonly seen in prostitutes and whore-like girls.

A casual invitation / threat used by an individual that is not afraid of fucking someone up.
