The feeling of high you get a period of time after you smoke a decent amount of weed. Hash Flash could consist of light headed-ness, dizzy-ness, impaired balance, inability to form words and other symptoms specific to the user. Usually a hash flash only lasts for 25-30 seconds, but can last for as long as 4 minutes.

When someone takes a picture of themselves in a mirror, the flash blurs out their face, resulting in flash face.
Did you see the pic she posted? Almost couldn't see who she was, there was so much flash face. Total fail.

A Reverse Flash is when you're pushing out a fat shit turd but midway your butthole clenches and it make the turd go in reverse.
Dale: "So yesterday i was so constipated that I had a reverse flash."
Ted: "Did it feel like getting anal?"
Dale: "Fuck you Ted."
