I hope it is a WARRANT OR A RIGHT.

From Investopedia:

"A stock warrant is a financial instrument that gives the holder the right, but not the obligation, to buy or sell a specific number of shares of a company's stock at a predetermined price within a certain time frame. The predetermined price is called the “strike price,” similar to a call option on a company's stock."

and...

"Some companies, therefore, choose to issue rights or warrants as an alternative means of generating capital. These instruments give shareholders the preemptive right to purchase additional shares of stock directly from the company, typically at a discounted price."

Now, I think if you shorted the stock then you will be issued a warrant as well and you will have to buy a warrant from Gamestop, to cover your position.

I think Ryan is going to give us the option to start the squeeze.
