fhin
A fhin person is somebody that seems to not have been able to grown entirely fat or remain entirely thin. The most common case of fhiness I’ve seen is the women that have huge butts and thighs but are quite thin and slender from the waist up. Another common case is that of people that are quite thick from the waist up but find their bodies supported by rather frail-looking, skinny legs. There are, however, variations, such as the entirely skinny person that somehow still manages to be flabby or the fat person that for some weird reason is as firm as an Olympian athlete.
