Abbreviation of "Filmed Vertically, Didn't Watch." Used to express a lack of interest in of watching a cellphone video that was filmed with the camera in an improper orientation, regardless of how potentially interesting the content might be.
I followed a link for a video that shows a unicorn having sex with a manticore, but the idiot who taped it held his phone vertically, so I just tagged it with a "fv/dw" and moved on to a video of the meeting between Hitler and the Dalai Lama.
