I'd like you to meet Rob, who sells edible undies that taste like broccoli. He's a real up-and-coming entremanure.

My client, who opened a Victoria's Secret store in Islamabad, definitely has the 21st century entremanurial spirit.

1. A person who sells bullshit for a living.

2. A person who is constantly starting new businesses that are absolute crap.
1. Dude, did you hear that Bill tripled his money day-trading penny stocks? Yeah, but don't forget he's a professional entremanure.

2. Trent and Blaine are starting their fifth internet startup. This one is going to enable companies to analyze fleet usage characteristics in real-time. They are two enteremanures of the highest magnitude.

An entremanure is a governing body that has the power to talk absolute bollocks while still sounding elusively motivational, thus giving an air of being powerful when, in fact, the speaker is actually a 17 year old business student with ginger pubes.
"Thinks he's a proper little entremanure that one, he's even got an obligatory "manager's" hard-on"
