A muffin top (also muffin-top) is a slang term typically used to describe a person's body fat that extends horizontally over the edges of the waistline of tightly fitting pants or skirts, visible when there is a gap between the upper and lower garment.
Muffin-top originated as Australian slang in mid-2003,[1] but has since become popular in other English-speaking countries.
[4] The Oxford English Dictionary added the term to its revised online edition in March 2011.
[5] According to William Safire, writing in The New York Times Magazine, "Muffin-top fills a lexical void" and "describes the roll of excess flesh spilling out primarily in front but possibly all around.
"[6] By 2007, the fashion for low-waist trousers and skirts had lost ground to higher-waisted garments, making muffin tops less ubiquitous.
