look up any word, like the eiffel tower:
 
1.
Piece of clothing or wearable accessory that conceals a water canteen. Used in harsh environments where dealers want too much money for a bottle of water and you won't make it thru the day without it. Safe sucks.
Concerts and events where the security folks won't let you in with your own drinking water supposedly for "security" reasons but really just to jack corporate sales of teeny bottles at 4 bux a pop. Just bring your Dune Jacket so you don't get gouged and you don't get sick either.
