A Flash Washer is someone in your office that briefly runs their hands (sometimes just fingers) under the water after using the restroom. Basically stating that their restroom activity did not warrant a soap and warm water hand washing.

possibly the best hip hop DJ that ever existed, pioneer of the scratch, along with the furious 5 have created the most original, creative and possibly most re-worked music ever.

On Graigslist listings that are there and gone in a flash. Listings that are on so short a time you usually don't know they were even there. I suspect that some people use software that alerts them when certain types of listings appear and the rest of use never see the listing. Craigslist seems to be going the way of ebay, professionals are crowding out regular buyers, and sellers.
That listing was posted 2 minutes ago and now it's deleted, another flash listing. I can't park in front of my computer, and the good stuff is always gone by the time I see the listing. I don't spend much time on Craigslist anymore flash listings have taken the fun out of it.

A “Bleach flash” is the act of shining a flashlight in someone or something’s ass hole with a rat nearby. The rat will instinctively climb in said ass hole completing the act.

Tyron: C’mon what are you talkin’ bout, why would you say that.
Jack: it’s just... everything kinda went downhill after she caught me bleach flash her sister.
