Jargonista 

A person who is able to use a variety of technical terms to ultimately say nothing meaningful, but somehow still manages to satisfactorily answer questions from senior management, all while sipping a Venti, sugar-free, non-fat, vanilla soy, double shot, decaf, no foam, extra hot, Peppermint White Chocolate Peppermint Mocha with light whip, upside-down, 1 pump of peppermint, 1 and 3/8 pumps vanilla, heavy whip-cream, 3 ice cubes, 1/4 teaspoon Nutmeg sprinkled on top, with green sprinkles, light cinnamon dusted on, stirred, with no lid, double cupped, and a straw

Largonistic 

Largonistic comes from the word "Largo", which is a musical term to describe the tempo and mood of the music. Largo is slow and romantic and dreamy. So when somebody is Largonistic, it means their head is in the clouds.
