Someone who is so sarcastic they forget the original point they were trying to make. A Minister of Sneers will spout such acidic verbiage that they often burn themselves in the process. A person who holds this position enjoys the process of cutting people (or things) down to a level above normal sarcasm. Often confused with an Office Monkey.

The Minister of Sneers made fun of the Republican candidate, but then fell silent when the Democratic nominee took the same position.
