When a trader holds a short position (i.e. a position established in anticipation of a price drop), he needs to close the position by buying the same amount of coins to lock in profits or limit losses. If a large number of short orders suddenly appear in the market and need to be closed, and at the same time there are almost no other short orders willing to sell in the market (i.e. lack of sufficient counterparties), then this situation may lead to the so-called "air-to-air squeeze event".
