Knobologist 

Someone who has a P.H.D. in the sucking of Knobs. One who gives great blowjobs.

Andy: "My girlfriend gives the best blowjobs."
Robert: "Yea, everybody knows she's a great Knobologist."

knowologist 

An individual who always contributes a perceived fact during a conversation despite being wrong, and will defend their statement blindly like a douchebag.

A know-it-all who has created a religion out of interrupting people with useless facts or opinions and believes they are always right.

Thanks for being a knowologist Jason
