muffin top n. rolls of flesh bulging over a waistband. Editorial Note: This term was nominated as one of the words of the year, voted on by the American Dialect Society January 6, 2006. It did not win. This term may have first been popularized by the Australian television show Kath & Kim. An episode of the American sitcom Seinfeld, “The Muffin Tops,” first broadcast May 8, 1997, spawned a different, short-lived usage of muffin top as a name for anything good. The 2003 citation probably does not refer to the bulging appearance of a midriff. The first 2004 citation gives a different term for the phenomenon and uses muffin top as a description of a different part of the body. (source: Double-Tongued Dictionary)
