A high velocity dual-angle (two-part/"split") cumshot created by the force of ejaculate around the cum-stuck center of the linear accelerator nozzle (cock-hole), resulting in a double splat of giz, typically on the face and headboard, the hair on both sides of the face, or in both eyes. NOT TO BE CONFUSED WITH Cuban Missle Crisis.
