Scootermom: RMOysters Repel Men

Scootermom: The only time I ate Rocky Mountain Oysters was when my girlfriends and I were studying for the bar, at the bar, and kept being approached by annoying men. We ordered some Oysters, and they magically left us alone. Man repellent. Very effective.

Question: In the day, how did you chase away annoying members of the opposite sex?
