What does the song Gayfish mean?

This song comes from an episode of the spoof anime: South Park. It's probably a spoof of Kanye not being able to understand a joke. The following is a joke: Do you like fish sticks? (Do you like fish sticks? The word for fish sticks is fish sticks, which is pronounced as fish dick, fish dick...) Yes. (Yes.) Would you like to put the fish sticks in your mouth? (Do you like to put the fish sticks in your mouth? The pun is intended to mean do you like to put the fish sticks in your mouth, implying that for the fish) Yes. (Answer still doesn’t catch the pun) Then you are Gayfish. (Then you're a gay fish. But in South Park, Kanye was teased and didn't understand the joke, so he caused a lot of trouble.) If you watched this episode of South Park, you know what it means.
