One step up on the comfort scale from "studio gangster."

Some are gangsters of their hood, e.g., bed-sty, BK. Luda was not so ambitious, deciding to be a gangster of just his bedroom. And, I mean, if you're going to restrict your realm of operations to just a single room, surely you can do better than being JUST a gangster. Shit, I'm the -emperor- of my bedroom. it's easy.

I would like a gangster for every room of my house. The dining room gangster will be a big hit at parties.

I'm hoping he means this:
