A lower back tattoo on a female that a male will used to ejaculate on when he "pulls out" during doggy style sex. This tattoo is also known as a "bullseye". Do not confuse a splatter mat with a tramp stamp. A tramp stamp is a female lower back tattoo that has not yet had the pleasure of receiving male ejaculatory fluids.
