a cheap button up cotton (or flannel material) "blouse" without sleeves. Usually worn by white trash or masculine females. The muscle blouse is usually worn un-buttoned and it pairs nicely with jorts. Most times this is also paired with a "hubby-beater". Most often found in conjunction with tattoos (specifically tramp stamps) and Marlboro Reds.
