The act of showering with 2 or more individuals to save tons of water. Started by AXE, in 2012, proposing that if everyone showerpooled for a year we could save 29 trillion gallons of water. Usually but is not limited to showering with like-minded acquaintance ...or an attractive stranger.. which could result in the next big Baby boom, or the biggest sexual transmitted disease outbreak in the history of history.
