FA is the common abbreviation of the two words 'female attention'. FA is well sought after by many alpha males in their secondary school education, resulting in the humiliation of one and the other drowning in the sweet pussy juices of the chosen female. The female herself commonly results to arm grabs, eye contact and general affectionate responses - all deemed as FA.

Short form for Forever Alone.

A Fat Admirer, or a guy with a preference towards big girls BBWs. And yes, they do exist, and no, a FA is not the same as a feeder. Contrary to popular belief, Fat Admiration is not a fetish, it's no different to a preference for redheads or short girls.

Short for Fat Acceptor or Fat Admirerer. Refers to one who is attracted to large or plump men or women.

A long, long way to run.

Fuck all (used in the expression Sweet FA, which originally stood for Sweet Fanny Adams)
