(noun) the saggy, drooping flesh that hangs from a person's body caused by rapid weight loss due to prolonged use of methamphetamine; particularly that of a previously overweight and/or morbidly obeseindividual
(sounds very similar to 'meth lab' when used in conversation)
"I wonder how long it took her to build up that meth flab." or "That meth flab destroyed her life."
On a morbidly obese individual, large flaps of skin hanging down below the waist, forming pockets of flab under the sweatpants, about where the pockets would be on real pants.
Usually observed on American rednecks carrying large misspelled signs protesting against the government.
Small breasts that take on no shape. Not indifferent to a slight stomach or arm fat. Only recognizable by the two nipples. Chest flab is most commonly found on Asian women.
"Hey, look at her tits. Oh wait, those aren't tits, it's just chest flab."
