1 n particular variety of meatball. 2 n bundle of sticks. 3 n grumpy old woman (uncommon). 4 n cigarette (uncommon). 5 n prostitute (uncommon). Brits do not use it as a derisive term for a homosexual man. In reality, the American definition is well known (if not really used) U.K.-wide, so most of the jokes involving the various other meanings have already been made. They all stem from the original Norse word “fagg,” meaning a bundled-together collection of matter. Do prostitutes come in bundles, I wonder.
