An excessive form of bingo wings. The skin must hang more than 8 inches from the arm and span from elbow to shoulder. The way you can tell if somebody has bingo banners is if that person looks like they're wearing a fleshy basejumping suit underneath their clothing.
Friend 1: Your mom has some serious bingo wings since she lost all that weight.
Friend 2: Yeah, they're bingo banners now.
Friend 2: Yeah, they're bingo banners now.
