MOASS - mother of all short squeezes. It's a trading strategy where a high volume of buyers drive up the price of a stock that has been shorted.

Gamma Squeeze - It occurs when the price of a stock surges in a short period of time, often associated with the purchase of call options to drive up the price. Option sellers will then need to also buy the stock, to hedge their losses, resulting in further rise of the stock price. Thus the buy-buy effect is further exacerbated leading to a stock price rally in a very short period of time.
