Here is my interpretation:
TWINK: under 30, typically early 20's / slim, skinny / fit - but not muscular / energetic
YOUNGBLOOD: REVISED - a bit more muscle than a twink - sometimes called a TWUNK (Twink/Hunk)
HUNK: REVISED - any guy who is quite fit, but not overly muscular, typically over 30
JOCK: anyone that is ATHLETIC but NOT a twink
MUSCULAR: anyone with bulging muscles that one does not get without using creatine, testosterone, or other supplements / body builders who train to build muscle
CHUBBIES: anybody with a keg instead of a 6-pack or folds of flab and love handles
BEAR: anybody with chest or back hair who is not a twink who is over 30
PUP/CUB: a twink with chest hair
MEGACOCK: one with a cock even half the size of that of RaphJD
