Contextually Important Nigger Lore
Kanye hates Jews. They created pornography, which Kanye and his cousin stumbled upon at an early age, inspiring them to start sucking each other's dicks for years. Kanye told his cousin they needed to stop, and then the cousin stabbed a pregnant woman and went to prison. This was a 'skeleton in the closet' Kanye has had to live with his entire life.
Then, one day, South Park released an episode about the following joke:
>Do you like fishsticks?
<Yes
>Haha, you are a gay fish!
Where, in the episode, Kanye West was the only one that did not get the joke, and thought everybody was making fun of him. He makes an ass of himself, and then the episode ends with him concluding that he actually is a gay fish, and he puts on a Borat-style swimsuit and goes underwater and starts kissing male fish.
Kanye responded to the episode on Twitter, lying that it didn't bother him, pretending to be a good sport about it. But in reality, he felt deeply humiliated and was seething at the South Park writers... for unbeknownst to them, he actually did have that gay skeleton in his closet, and many millions of people watching a cartoon about him being gay cut deep.
With his recent tweet on the subject, and this song, he has admitted this dark secret to the world.
