jinkster 

Scottish word used to encompass the art of being a player, pimp & O.G all rolled into one.

Man, that guy Jinkster just walks this land.
He's going snowbombing next year, he's going to get so much ass it's not even fair. He can get totally mingbagged all night and be ready to get right back on it the next day.

Jongstery is to Mystery as The Frugal Artist is to The Pickup Artist.

Jongstery only shops clothes on clearance - you'd better be using extra coupons and discount codes to make the deal sweeter!

Jankster Gangster 

From the word Jank meaning messed, screwed or fucked up. This is a person who walks around like hot shit on a golden platter but acts more like a cold turd on a paper plate.

He asked me out on a date, then that jankster gangster left me with the tab.
