Foy is actually a term for the smell that accumulates between a mans balls and his arsehole, as in Gringo's arse and foy smell. It is an unusual musty smell that is surprisingly hard to rid despite a decent personal hygiene regime. Often associated with physical activity and sport.

Get the foy mug.
A human being that is angry, fat and smelly. A Foi Foi will typically have dirty red hair and will not shower for several months at a time. During this period of time he will also grow a filthy red beard accompanied by a rank, noxious stench that only cows can tolerate. Due to this fact the Foi Foi does not have any friends and finds company in the form of common farm animals. It is also a member of the Ag club.

The day to day calendar of a Foi Foi includes, mouldy-Monday, toejam-Tuesday, wankstain-Wednesday, thigh pimple-Thursday, fungus-Friday, septic-Saturday and seedy-Sundays.

I strongly suggest that you do not seek out a Foi Foi, but if you really want to they are commonly found at the agricultural plot of their local school or a nearby hobby farm.
