LBF is similar to the gay best friend. A girl who is "one of the guys." She can engage in bro activities such as watching sports, eating hot wings, and checking out hot girls. The boys feel that they can be 100% "bro-tastic" around her without being embarrassed by their actions. A LBF can also act as a wingman at times.
