To take a concept that is relatively simple and that could easily be expressed in common layman's terms and make it so technical that you have to be asked for further explanation; thereby making yourself appear smarter.

Joe: Anyone know where I can buy a llama?
Nerd: Well you don't want the UAE llama as they are disproportianate in the flank and shoulder which affects their intermediary gait. You should purchase a Columbian llama using an offshore account you can set up online and then import it with Unix.
Joe: wtf?
Nerd Translator: He said buy the brown llama. He was just upnerd-ing it.
