Etymology

Origin of flabby

1690–1700; apparently expressive alteration of earlier flappy, with same sense; see flap, -y 1; compare late Middle English flabband (attested once), evidently with sense “flapping”

Explanation

If you're flabby, you're out of shape, with a soft, slack body. Some people join a gym when they're feeling a little flabby. People who are flabby aren't star athletes — you may be flabby after a long, cold winter spent mostly indoors, or feel flabby as you struggle to hike up a mountain. You can describe other things as figuratively flabby too, if they're a little sloppy or weak. Flabby writing is messy and disorganized, and a flabby politician is ineffective. Flabby started as flappy, "softly fleshy," in the 16th century.
