We use words that carry the weight of something... big. Something big. Really really big. Then those words smack against your dumb forehead. Like ta - dow. How you like me now?!
We use words that people in boardrooms will be using in 6 months. We invented synergy while we were coming up with the concept of "outside of the box". We piss organic while fighting groupthink.
Talking down to people is an art. You probably wouldn't understand that though with your phony ass degree. We use big words that you nod at, then Google while you're "in the bathroom".
We used the word lexicon before there was a spoken dialect. On Saturday mornings we sell $10 words for $7, but only because we were selling word futures the previous night.
