F.I.S is an abbreviated term for Fetal Ink Syndrome. Fetal Ink Syndrome happens when a pregnant mother gets a tattoo while pregnant and the baby is born with a distinct black circle on the forehead, under developed or malformed cranium, and is destined to have a shitty future due to poor parenting skills by the mother.
That poor baby must have been born with Fetal Ink Syndrome.
That stripper's baby will be born with FIS.
Son, you must've been born with FIS, cuz you an idiot.
