I was just reading something a few days ago and a part if it was describing a type of person. Half way through, I thought "wait a minute... is that me?"

It was a description of problem people, who seem to be able to cause problems in organisations, decision making and more:

...Think about the man who…

• Speaks for a long, loud, first and often
• Offers his opinion immediately whenever someone makes a proposal, asks a question, or if there’s a lull in discussion
• Speaks with too much authority: “Actually, it’s like this…”
• Can’t amend a proposal or idea he disagrees with, but trashes it instead
• Makes faces every time someone says something he disagrees with
