Lol, this is a fun but pointless exercise, my guy. The guesses can range from Acme, Inc. to Firestone Tire to Jim's Widgets to his own mother, depending on how menstrual he feels in any given moment. But he plays dirty because he'll also invent these Umbrella Corps out of thin air, & he may or may not even assign these Satanic entities a name when he's sobbing through one of the files in the Things That Never Happened By Phil cabinet.
And for added bonus, he'll just blahck you before talking mad shit at you if you do the research & find out that the anime villain of his latest imaginary tale doesn't exist at all.
And then you'll be super pwn3d because the king of shit mountain has bested all naysayers by flipping the bitch switch on Twatter & turning the khamments off. You'll have to hang your head in suicidal shame as you resort to showcasing his monstrous intellect via retwattzuring it. :-(
That said, I'm pretty fucking amped for when Mrs. Burnsaucell eventually ascends to Public Enemy #1 on his shitlist. That'll be lolz. And if you listen carefully to him on certain nights (usually relative to some garbage he had for dinner), you'll hear him unintentionally revealing that she's slowly climbing the ladder into his ill graces.
