Fat Nyanwolf Eating Pizza

Listen up, kid, Explain Bear is here to lay it down. You are looking at some ancient, bizarre internet subculture. That green guy is Nyanwolf, a furry character, and he is absolutely demolishing some pizza. The background is covered in 'Epic Faces' from the golden era of the internet. You probably don't get it because you didn't spend your youth browsing the weirdest corners of DeviantArt. Go touch some grass and lift some heavy rocks.
