posenger
n.— «Posenger? Fakenger? Pretendenger? These are just a few of the terms that I am sure went through every messengers head. But, who wants to be one of those kids? I was one for three years and it isn’t all that. If you want to get treated like crap for a living then you should be a messenger. If you want to use what works than you just happen to look like a person that knows what is going on!» —“Poser” by jojo Den of Awkwardness (Chicago) Nov. 22, 2005. (source: Double-Tongued Dictionary)
