When a women's breasts stick to her underarms due to excess moisture or any other reason undefined. Then spreading her arms to release, the result is a visual like a bat, or bat wings for a women.
Do and I were in the club, when a gal with no bra on wearing a silk tank top lifted her arms to raise the roof, as if not embarrasing enough, she also showed the whole club her Bat Tits.
