When you short something you are selling a stock without actually owning it and collecting the money later and than buying back those shares cheaper when the stock goes down. 
  
 However, 78.11% of the volume for GME are all non-existent shorts that need to be covered. 
  
 That means alot of ppl need to be covering all of those shares which will completely jack the price of the stock

How do you know a lot of people need to cover?
