When a woman gives a blowjob to the Pizza Delivery guy that's delivering the pizza to her. It is also known as a 'Sloppy Pepperoni.' It obviously only applies to blowjobs, thus a man cannot use this expression unless he will be performing the act on another man.
Example: "OMG Kara, you are not going to believe what happened yesterday: I gave a sloppy sausage to the Domino's delivery guy as soon as he came to my door..!"
(Can be done with any woman but busty is preferred) When a man proceeds to be on top of a woman with a large chest and shoves his penis in and out rapidly and furiously while buttercream/any other icing is spread on her nipples . The man proceeds to grab onto her breast, squeezing violently while still inside her and eat the icing while trying to get her to orgasm.
I gave Jenny a Sloppy Buttercream and when she squirted her nipples were red and she was asking for more!
