mom jean
n.— «Avoid at all cost, what is known as the “mom jean,” that pancake flat butt that comes from high-waisted but tapered-leg jeans. Timmins recommends a full-leg trouser style, which is more forgiving and not as tight on the stomach. One such jean is from denim brand Habitual. It has a paper bag waist style—loosely gathered and belted.» —“High-waisted, wide-legged jeans make a comeback” by Derick Chetty Toronto Star (Canada) Aug. 24, 2007.
