This kind of language usage isn't limited to fitting in socially in the business world.

People use overly-elaborate language to appear intelligent or innovative, too. I once spent some time learning a martial art whose founder had replaced all of the standard names for movement and techniques with novel, quasi-technical-sounding ones.

"Multiple attackers" became "plural assailants", "breathing technique" became "respiratory enhancement". "Sparring" became "fisticuffs". Etc.

It was maddening, because he would correct students who slipped up and failed to use his terminology.
