A Saturday that is filled with much merriment and vivaciousness. A Saturday where life is lived like a drunken libertine. A strong, life-affirming Saturday.
Comes from the combining of the words "Saturday" and "diesel".
I can't wait for this Saturdiesel. We gon grill, drank beerz, ride jet skis, play with some baby panda bears, participate in an wild orgy, fight a celebrity, give birth to a albino gorilla, and go see a movie at the IMAX. IT'S GON BE SATURDIESEL!
