fornobulate
using phony made up words to confuse and annoy egotistical people with big vocabularies

In college there was a guy in our dorm who tried to impress everyone with his large vocabulary. I got my friends to start using this made up word "fornobulate" to confuse him. We always used it in a different context so he never could guess the meaning. It drove him crazy. When he finally asked me what it meant, I said, "Get a dictionary and look it up, Mr. Vocab." He came back and said it wasn't in Websters. I replied, "What? You can't spell?" So 30 years later I officially give "fornobulate" a meaning!
If a friend tries to impress you with his large vocabulary, fornobulate him!

The fornobulation process used on the egotistical nerd was successful.
