1. A rare, massive "Short Squeeze" event in the financial market that is devastating enough to completely bankrupt large hedge funds negatively affected by it, creating a broader impact across the market where many securities sharply fall in price while others rise dramatically in price.

Coined during the $GME Mother of all Short Squeezes (MOASS) Saga by retail investors on Reddit (most notably from r/superstonk).

In a Market Moonsoon, securities that the bankrupted market participants held "long" positions of are rapidly sold, significantly damaging the price of those securities, while the securities the market participants held "short" positions of rise significantly as they are forcibly covered after their prime broker takes on and closes the all positions.
Toxic Hedge Funds and Market Makers caused a Market Moonsoon after the fraudulent trade practice of "naked shorting" $GME backfired when retail investors bought and held the stock, causing $GME's price to reach astronomical levels while the price of many other securities held by the toxic market participants crashed while they were forcibly liquidated after being defaulting.
