Sometimes referred to as grannie panties, momma briefs are generously portioned under garments that often include a "control top" and are exceptionally comfortable. While there are many theories on how the name came to be, it is widely believed that men, after seeing someone wearing these undergarments, would exclaim: "Oh, mama!! You look so hot in those undies!!! This is going to be brief."
Check out those mama briefs . . . do you think they come in flannel?
