Portmanteau of flabby and muscular. A flabscular individual is one who has lost a significant amount of weight and put on muscle mass without undergoing skin removal surgery; the result is large flaps of loose skin marring an otherwise impressive physique.
The man prided himself on being able to overcome obesity and live an active, healthy lifestyle, but rarely showed off his muscles because of his flabscular physique.
