Rusty Gerber 

Is the act of taking expired Gerber baby food, smearing it on a woman's anus, and then proceeding to eat the subject out while the woman is on rag. Once finished, you slide the tampon out of the woman's vagina and plug up the anus before giving her a feisty smack on the ass. Then, one puts the woman on a leash and leads her to be bathroom and commands her to poop out the tampon and remainder of the Gerber baby food.

Once the woman has pooped, you force her to turn around and proceed to give her another rim job while she sings "O mio babibo Caro" to the shit in the toilet.

I heard Gary and his bitch got kinky last night - He gave her a rusty gerber
