turdfester 

An insult (naturally) implying nothing in particular about a person other than their being on a par with a festering turd in value. Don't know if this is local to Essex or more widespread or if, indeed, my small group of friends had exclusive use of it.

(enter name here) is a turdfester or even just an interjection of "turdfester"

Nickname for the boss in a dysfunctional hierarchy since s/he essentially tells you when and where to shit.

Sorry buddy, I can’t do anything for you yet, I’m waiting for the Turdmaster to drop his giant turd so that I’ll know how to handle things.

turdster 

A prankster who throws a turd into a discussion. Superficially, they are just another participant. But in reality, they are less interested in persuading others than in making a splash.

The back and forth in the comment section was going well, until that snickering turdster joined in.
