fauxthority

1. an adjudicating person or body that is spuriously invoked in order to win an argument or discussion, especially where no such body actually exists.

2. an air of supreme knowledgeability and pretentiosity, projected by a person who will speak at length and with great opinion, on topics of which he or she actually has only a p-ssing grasp at best.
(in this example, both hmb and drb are using fauxthoritative arguments, and both are displaying fauxthority.)

hmb: sylvia saint’s finest -sset is her bottom.
drb: you lie. it’s her br–sts.
hmb: surely not. for br–sts, q.v. brianna banks, asia carrera, et al. theirs are much larger.
drb: your argument hinges on the theory that quant-ty is preferable to quality. in defence of the alternative view, sylvia saint is entirely natural, as can be deduced when viewing her in the reclining att-tude.
hmb: be that as it may, her br–sts are much smaller, at most 0.94 british standard handfuls. by comparison, asia carrera weighs in at a hefty 2.09 bsh.
drb: yes, but is it not spoken in the book of erogenis that “reckon thee the food in thy bowl the same as thou wouldst reckon the t-ts on thy concubines: that any more than a mouthful will be wasted?”

(discussion continues as both speakers get to indulge their vanities in this verbal equivalent of public masturbation.)
a sense of non-existent authority. typically, an overzealous security guard that believes he/she has some sort of legal authority because he/she is a ‘security guard’ when in reality, security guards have 0 legal authority or law enforcement duty since they are not peace officers.
security guard: “hey what are you doing?”
person: “taking some photos.”
security guard: “do you have an id on you?”
person: “are you a police officer?”
security guard: “no but i am a security guard.”
person: “aka fauxthority and you have no legal authority and no reason to ask to see my id”
security guard: “but i’m a security guard.”
person: “um sorry no i’m not giving you my id. bye. go beat the power pole off.”
