A mouthbreathing illiterate moron's mishearing and subsequent misspelling or mispronunciation of the word "comeuppance." The combination of "cum" and "muffins" adds hilarity to the usage of the term, as the word is typically placed in the syntax as an object to be received, as a result of karma, by a person perceived to have committed a wrong.
Yeah, that asshole screwed my best friend after I loaned him 400 dollars, but sooner or later he's going to get his cumuffins.
