An effect caused by smoking a seed in a bowl(as in the bowl of a pipe,bong,zong,hooka,etc) where the seed explodes because it gets so hot when you are lighting the bowl-o-weed. This happens most commonly when you are smoking shake,
shitty weed,or when you get skimped on a
bag of weed by your dealer.
(For the slower people, its short for dank
explosion and when you say it abbreviated it makes an "s" sound, not an "x" sound)
