A male having sex with a random female, not to be used with people in a relationship. Obviously skinboat means penis and tunatown is the vagina.

When you fuck a girl while she is on her period and get blood on your penis, then draw a Z on her chest with her own blood.
Jim was banging Bertha and pulled his dick out, noticing the amount of blood on his penis, he drew a Z on her chest giving her a red zorro.
