Looking good, but not overdoing it, is one possible interpretation of the abbreviation "HWP" used in personal ads or in dating chat. Literally standing for "height/weight proportional," using "HWP" in a personal ad lets potential friends know that you are within the normal weight range for your height. It sets you apart from other body types.

Height/weight proportional indicates that you are within the healthy range for your age and height, setting you apart from the "BBW" -- big, beautiful woman, the "BHM" -- big handsome man, the "BB" -- bodybuilder, or the "P" -- petite person.
