Dirty Mills 

When a male fucks another male in the ass so hard with a BBC so it gets so wide open. So that when he eats something it will simply fall out of him. Typically using cum or blood as lubricant.

“He gave me a Dirty Mills so when I ate my lunch it fell right back out!”

Very different to the traditional definition of dirty milkshake, but we don’t talk about that.

Sophia was disappointed to find out that the first rule of Dirty Milkshake Club is that you do not talk about Dirty Milkshake Club.
