The back-side lesbian, or more commonly known as the BSL, is a male individual that looks remarkably like a lesbian from behind, complete with woven choker necklace, short, boyish haircut, shapely female form, and undersized genitals. Studies have shown that a BSL is willing to shove a large dildo
far up his ass for only 50 dollars and many have unhealthy fetishes for comic book heroes, often using Batman posters as masturbatory aids. Furthermore, BSLs have an uncanny ability for arts and crafts and eating pepperoni calzones, but that's about it. BSLs have a strong aversion to Segalls, as well.
