The upper echelon of being a complete douche bag. Not the useful, clean, vinegary fluid that goes in, but the useless, cottage cheesy, foul smelling mucousy substance that comes out.
That dude marcus is a fuckin tool bag. Yeah dawg, he's a total bag of doosh waste.
A troublemaking little skank who gets into all kinds of mischeif. Usually hyperactive and sneaky, not rare to resemble a rodent of some sort (i.e. rat, mouse, meerkat, prarie dog, ect.). A complete klutz who ruins any situation as to be sneaky.
Larry: “Look at that guy with the stunna shades, popped collar and flat billed ball cap covering his man bun. Looks like he’s headed into Starbucks to find a safe space.”
Joe: “What a mega dooshkabob! So sad... let’s go get a shot and a beer to ward off any of his dooshness rubbing off on us!”
