Types of office colleagues that drive you mad revealed

From the 'shoulderbeast', who just likes to stand stalker-style behind you, to the 'panic monster', who is nervous and jittery all the time, an expert has revealed the types of co-workers that you just can't stand.

First of all, there is the 'idea killer', a worker who lacks creativity and shoots down others new ideas, and then there is 'gloomo' who sucks the life out of every co-worker with his negative energy, the Huffington Post reported.

Another type is the 'chief accent officer', who uses his accent to hide the fact that he does not know what he is talking about, not to mention the 'name-vomitter' who likes to brag about the various agencies he has worked for.

Then there's the 'creepozoid' with his sexual innuendos and 'pervoceros' with his perverted nature.
