fognozzle 

A contemptible, annoying, and or useless person.

Larry is always making me do his printing on the copier because he is a fognozzle.

cognozzle 

1. the tip (nozzle) of a device used to deliver enemas or colonics; usually it's not very clean.

2. someone you don't like and can't trust, who acts like a complete asshole most of the time

That dude in my lab is such a cognozzle. He's always stealing my ideas, eating my lunch, and taking credit for my work.
