Waar komt de uitdrukking "like a boss" vandaan?

-Het komt van een lied uitgezonden op SNL:

The phrase stems from The Lonely Island‘s single “Like A Boss,” a parody of the Slim Thug song of the same name.[1] Featuring Andy Samberg and Seth Rogen, the video premiered on Saturday Night Live as a digital short on April 4th, 2009. In the video, the Boss (Samberg) is asked to go over his daily activities during a performance review by Rogen’s character. While it starts out with daily office tasks, the lyrics evolve into impossible activities.
