Get the ninjamug. A severely autistic, ligma patient who can't seem to get any better. He denies his illness all the time, that's only because Ligma has corrupted his brain and memory functions specifically. Who also tries to hide his true colors on stream all the time but we all know he wants Ali-A's fat cock.
