Butch is a term used in lesbian and gay subculture to describe an LGBT+ person, typically a lesbian or otherwise sapphic woman who has a masculine gender presentation. The term butch tends to denote a degree of masculinity beyond what would be considered typical of a tomboy.
Butch women will often dress in masculine clothing, and typically present themselves in a more stereotypical masculine way, such as having short hair, not wearing makeup, and not shaving. Butches are also commonly thought of as having more "masculine" interests, such as sports, mechanics and other hands-on jobs. Some butches will take on masculine nicknames, and some may use masculine pronouns. Some butches bind their chest or take masculinizing hormones to appear more masculine. Despite this butch women are still women. They can be cisgender, transgender or any other gender modality. This label can also be used by non-binary people. It is not uncommon for butch women to face harassment or violence because of their appearance.
Traditionally, butch has been used by individuals who are attracted to femmes. For some butches, this attraction to femmes represents a strong part of their own identity. However, some butches are attracted to other butches. This phenomenon is commonly called "masc-for-masc" or "butch-for-butch".
Butch is sometimes used as a non-binary gender on its own, particular by people who have a complex relationship with gender or womanhood due to being butch or being sapphic. In a 2015 survey of non-cis people in the USA, 5% of respondents (about 1,385 people) were butch.
