That is fucking disgusting and I hope that PPP wasn't that inconsiderate to his best friend.
PPP in his "It's a Sad Day" video seems to try to pre-empt Surfer telling everyone that he was supporting PPP. He says that he gave Surfer his worldview. I think
@MrYumYums is correct and it was an abrasive living situation with two co-dependents.
I don't think that Surfer is smart enough to lie about PPP crashing on his couch, I suspect that it's Surfer who is the only one on the lease. PPP was there to correct the record with his interjections, almost as if he was trying to save face with his audience.
