Another term for ABV, or Already Been Vaporized, marijuana, after it's been used up in a vaporizer (i.e Volcano, DaVinci, etc.) to it's fullest vaporizing capacity. It ends up looking very dark brown and granular, much like Folger's instant coffee, hence the name.
That grass looks pretty folgered, time to reload the vape.
