1950s: back-formation from flabby.

  • Flab was formed in the 1950s from the late 17th-century flabby, itself a form of flappy (late 16th century) from Middle English flap, which probably, along with its further variant flop (early 17th century), imitates the sound of something flapping. The slang use be in a flap about something dates from the early 20th century. Flabbergast, first mentioned in 1772 as a new piece of fashionable slang and probably an arbitrary invention, may have been modelled on flabby. Flaccid (early 17th century) comes from flaccus, the Latin for ‘flabby’.
