the jelloish dangling sack of extra skin and fat that hangs around a person's elbow (usually a fat or old woman). A combination of the root words Jello and elbow. Usually associated with cankles and a gunt.
Damn...that nasty GILF has got some cankles, a gunt, and jellbows.

She doesn't have elbows, them be jelbows.
