Fit As Fuck.

This acronym for the term was coined in Essex, England, and since then has been frequenly used by the whole teenage age group, especially those in the Alternative music scene. It can quite commonly be found on Myspace, a popular internet socialising website.

Please note: F.A.F. has a dot after the second F to add emphasis. The conventional F.A.F is more widely used. The extra dot may also added to avoid the certain 'chaviness' surrounding the more common form.

It also quite acceptable to use F.A.F. in normal speach.

FAF - or 'Flex As Fuck', fullout - is used when something isn't just flex, but more than flex. It can be used in a number of situations, when something is just to flex for words. It can come in especially handy when one is shown a picture of one another and you are trying to describe a pose, facial expression, etc.

There is also an hand symbol / gesture to indicate that something is FAF. The symbol uses two call me sign, with crossed pinkies.
