I assume a naked call would be me selling with 0 contracts.

Selling a naked call is when you have no stock in that ticker. Because options are buying and selling the rights to buy and sell 100 shares of that ticker. 
  
 Conversely, a covered call is when you sell a call option but have 100 stock to back it up. 
  
 I repeat do not sell *naked* calls or puts unless you have the capital or stock to back it up. Or at the very least when you understand what the implications of being on the wrong end of one is.
