Mississippi Oil Change Edit Meaning

1.

When you give one of your sisters an enema and then take her used enema water and give your other sister an enema with it, it is called a Mississippi Oil Change.

I read this on SoulSeek today. Some kid in a chat room is named Mississippi Oil Change. I asked him if it was like a Mexican Oil Change but he gave me the definition seen above.

See oil, enema, change, incest
