Essentially the 4/20 at the other end of the calendar and celebrated on the day after Thanksgiving ("Black Friday"), Danksgiving is a holiday spent with friends as opposed to family (since most people spend time with their families on Thanksgiving anyway). Most treat it as a potluck, with everyone bringing their leftovers from Thanksgiving for the collective group. Celebrators typically enjoy massive amounts of ale and marijuana as well.
"Happy Danksgiving Toph, what are you dankful for?"
"I'm dankful for this dank turkey, dank Yuengling and dank kush."
