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.
"Dude man, you should totally go showerpooling with those cheerleaders over there, you'll get wet together, and save water"
