What does flabby mean?
Flabby is an adjective describing something — most often flesh or muscle — that is soft, loose, and lacking firmness or tone. It is the everyday counterpart to the more clinical term flaccid, applied to arms, stomachs, and other body parts that have lost condition through inactivity or age. The word also extends figuratively to anything perceived as weak or undisciplined: a flabby argument lacks rigor, flabby prose wanders without focus, and flabby management suggests poor leadership. In all its uses it carries a mildly negative connotation, though when people describe their own bodies as flabby the tone is often self-deprecating rather than harsh. The word derives from an older sense connected with things that hang loose or flap, and it has spawned related forms including flabbiness, flabbily, and the noun flab. Versatile and instantly understood, it remains one of the most common ways English speakers talk about lost muscle tone and general laxity, whether physical, intellectual, or organizational.

Etymology of flabby
Flabby emerged in English in the late 16th or early 17th century, apparently as a variant or derivative of older words meaning to hang loose or flap, such as 'flappy' and 'flap'. It came to denote flesh that is soft and pendulous, and by the 18th and 19th centuries it was firmly established both for bodies and, figuratively, for weakness of character or argument. Related forms include the noun 'flab', a 20th-century back-formation popularized by fitness culture, along with 'flabbiness' and 'flabbily'. Its broader relatives include 'flap' itself and 'flaccid', borrowed from Latin, which shares the sense of limp looseness.
