Definition

Someone attracted to two or more genders—a valid identity on the spectrum of attraction that doesn't require perfect gender balance or preference consistency. Bi people exist in beautiful complexity, and their orientation is just as real as anyone else's.

Example Usage

My coworker came out as bi last month, and everyone's been supportive and cool about it.
