Do you know what a cupcake fart is? No, its not farting on a cupcake. Its a term that younger people use as kind of a joke! Well you, My joke of a friend, are the butt end of it (pun intended). A cupcake fart is where you first ask the person if they want a cupcake. They will always say yes. You then fart into your hand and very quickly throw it at the person. Haha, joke is on you because Im gonna cupcake the crud out of you! What? Did you think I would hang out with someone like you without there being some intention? Hah!
