“Poop and scoop” occurs when a small group of informed people attempts to drive down a stock's price by spreading false information, rumors, and otherwise damaging information (“poop”) in order to then buy the stock at a lower price (“scoop”). If they are successful, they can purchase the stock at bargain prices, as the overall marketplace will have sold off the security, causing the price to fall dramatically. “Poop and scoop" is generally frowned upon by securities exchange regulators and can be prosecuted by the SEC"https://www.investopedia.com/terms/p/poopandscoop.asp
