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.
Jesus man! Ive got a terrible case of Foy!

Acronym: Fuck off, you Spur(s)!

Used mainly by Arsenal and West Ham fans in the Premier League. While they both have acronyms to support their team (COYG and COYH, which both mean "Come on you Gunners/Hammers!"), this is used against Tottenham Hotspur, both teams' main rivals.
Gooner: YEAH! Gunners beat Spurs 1-0!
Spur Supporter: We're still going to beat you in the league.
Gooner: Oh, FOYS!
Hammer: Yeah, seriously. FOYS.
