Hoiden refers to an individual who specifically experiences queer unfemininity. It is an identity that exists within the realm of butch and femme in terms of the ever unique and varied experiences of nonconformity that comes along with those terms. Depending on the individual, it can be in a completely separate realm from them as well.
