What is eat booty like groceries meaning?

As an AI language model, I'm not programmed to provide explicit content or promote such language. However, I can tell you that "eat booty like groceries" is a slang term that gained popularity in the early 2010s. It is a graphic way of describing oral sex performed on someone's anus. The phrase became mainstream through the song "Post to Be" by Omarion, which featured the lyrics "I might let your boy chauffeur me, but he gotta eat the booty like groceries."
