WinnerBoi was the username of a human who made the winning bid on the Doctor's TARDIS in a GalMart online auction. He wanted to cancel his high bid when he realised the Twelfth Doctor still had the TARDIS key, but had to pay for it. The Doctor created a Trojan virus, forcing the TARDIS back to him and declaring it as bootleg or counterfeit, and he had the GalMart computer pay for an anti-Trojan, transferring the money to WinnerBoi for the amount he had paid to buy the TARDIS.
