Fas

Fas is a shorter version of fail. It is easier to use and is extremely catchy. Because it's so short it's really useful for when someone fails at something.

- Someone trips and almost falls but its really funny. You say: "Ha fas"

- Your friend gets asked to do a chore by their parent. You say: " fas"

Fat Ass Syndrome - A serious medical condition whereby a woman's (or in rare cases a man's) ass is unproportionally large as compared to the rest of their body. This affliction has four levels of severity - mild, moderate, severe and uncontrollable. Generally this is a congenital and unreversible condition that cannot be cured via healthly eating and exercise.

Alan immediately backed out of his wedding when he noticed his fiancee was showing early signs of FAS.
