r/wallstreetbets, also known as WallStreetBets or WSB, is a subreddit where participants discuss stock and option trading. It has become notable for its colorful and profane jargon, aggressive trading strategies, and for playing a major role in the GameStop short squeeze that caused losses for some US firms and short sellers in a few days in early 2021. The community is run by u/OPINION_IS_UNPOPULAR, who has moderated the community for over 9 years. From Wikipedia
