A buffoon or jester acting as a boss for any medium to large size office. He circumvents, cheats, deludes, dissapoints and finally ensnares prospective clients using jokes, antics, and sheer braggadocio. Arse Clowns' obsessive tendency for bullshitting stem from being born with absolutely no talent and often suffer from slight brain damage, a condition which incongruously causes them to swagger about in a cocky manner.
"Why the hell is that guy such an arrogant prick? He has no skill or intelligence, in fact he's quite ugly as well!"

"He's an Arse Clown"

i thought i bloody well invented arse-clown, but i guess not. an arse-clown is someone who tools around and is a bit weak instead of getting the job done.
that bloke there with the side burns and the john lennon glasses, talking about how much he earns in the IT industry, my best guess is he's been an arseclown from the get-go.
