/Lit/ bros, I come to you needing a bit of help. Yes, I've used every search engine I could, and yes, I'm forgetful. Pardon me on those aspects. Anyways, I need help finding the title of a book. The basic premise is that it's mocking the United States in the most offensive way ever. It..Actually offends everyone. How it begins, I cant remember. From what I remember, the main character receives his food/drink through his toilet in his apartment, and there's a homeless guy that lives there or something along those lines. People are fat and ride mobility scooters everywhere. There's some parts that are beyond all words graphic in their explanation of the events. Yeah..My memory is a bit fuzzy, but all the help I can get would be greatly appreciated. Thanks in advance.
