A massive stream of semen caused by extreme stimulation of the male penis or female clitoris that shoots bodily fluids out the urethra at such high velocities that it may cause the cumblaster to shake violently and the cumblastee to be knocked backwards. Cumblasts can cum in a wide range of sizes from "bone bouncer" to "erectile kamikaze" and often take lots of practice to pull off. The cumblast was first performed by Mike Oxhard on the now defunct porn series "Drench it or Wench it" in a scene where porn actress "Messy" Jessie had just smacked Mike's erect penis while he was on viagra. Most cumblasts are fun to watch from afar but are painful to perform.
