Colligerent 

An adjective that has no meaning whatsoever. Used mostly in conversation to make yourself sound smarter than everyone around you. If someone asks you what it means, don't give them a straight answer. In fact, don't even tell them that the word doesn't really exist. Let them figure it out.

Dude, stop being so colligerent. You're embarrassing yourself.

coliferent

A word used to make people look smarter. Really. Try using it in a class discussion and see how many people pretend to understand. Also, 'coliferent' can be used as ANY part of speech, and mean anything you need it to.
