Splendid! Meta-Physical has offered a rich etiological explanation for the relatively under-researched phenomenon of gimmickogenesis (gimmick creation). He addresses the question of this thread with focus, and he employs both theory and observation to locate the creation of added pseudonyms (i.e., noms de pump) on a bodybuilding forum to certain compulsive traits within those who are pathologically attracted to the activity of bodybuilding itself – e.g., inter alia, (i) to a predilection to embrace superficiality, e.g., in using PEDs to perpetuate some form of artifice (i.e., artificial exaggeration or perhaps even deceit); (ii) to inventive flights of fancy which imagine and wish for a different appearance of the self; (iii) to the employment of this "new self" toward the goal of gaining recognition (both positive and negative) from a very limited subset of society -- especially from those who have hitherto withheld such satisfying recognition; and (iv) to the release of repressed anger in the form of getting one's goat, directed especially to the incorrigibly stupid.
In Freudian terms, we might claim with Meta-Physical that a strong response to gimmickry requires an assortative mindset (i.e., a kind of 'like responding to like'); in other words, that the antecedent phenomenon of gimmickogenesis and its consequent elicitation of gimmickorge (gimmick wrath) emerge from a shared condition of weak ego strength, which is not only roused to creative energy by the abnormalities of the "four D's, deviance, distress, dysfunction and danger," but also agitate the ire of certain cognitive constants (known in the literature as the five D's, viz. dummies, dullards, dimwits, dolts, and dopes) that are incapable of the higher-level thought required to dismiss the lure of gimmickry.
Plausible and well done.
