Pingstain is a tenacious cummy blemish on ones’ garment. Usually caused by orgasmic ejaculation of the male’s reproductive fluids after he reads an erotic text message or email pinged over the internet. His sperm exits the penal orifice propelled on a trajectory to inconveniently attach to the surface of said garment with an initial globular voluminous appearance. Subsequent exposure to decay and evaporation reduces the gift to a watery slime that infiltrates the interstices of the finely woven fabric to dry into a pertinacious pingstain blemish.
