It's a remark you make when you either hear someone (a scratter or total scrubber) say something disgusting or see someone do something deplorable.
Walking down the street Dave turned to look across the street and saw someone having a piss in street in broad daylight , Dave, shaking his head mumbled to him self, he said "Scrub out...."
to scrub it out, is it a girl or guy to wear something very relax or scrubby, most of the time sweatpants and/or sweatshirt. a day were they "just don't care", but really they do, and are usually wearing victoria secret, so, they are scrubbing with a very clean scrubber.
Girl 1: I like you outfit.
Girl 2: Yeah, i decided to scrub it out today, my hair looks like shit.
Girl 1: Oh, well, I don't think so.
