Butch is a masculinity grown inside queer life, documented through decades of bar culture, softball leagues and lesbian community history. It's broad enough to hold women who are firmly women, people who say butch is its own gender, and transmasculine people or trans men who kept the word — all of them butch, even where they'd define it differently from each other.
Boi is different in flavour: masculinity without the manhood, often specifically youthful or boyish rather than the more grown, settled masculinity butch usually implies. The spelling and much of its use grew out of Black American English and hip-hop, carried into queer use largely by Black lesbian and queer communities. It also has meanings outside gender entirely — a role in leather and kink separate from the identity sense — and there's no agreed definition even among people who use it for themselves.
How to tell them apart
- Butch tends to read as an adult, settled masculinity. Boi tends to carry a youthful or boyish quality, even when the person using it isn't young.
- Ask about the word's roots: boi's spelling and lineage trace specifically to Black American English and hip-hop, carried into queer use by Black lesbian and queer communities — that history isn't shared by butch.
- In kink and leather contexts, boi can be a role rather than a gender identity at all, which isn't true of butch — butch doesn't have that second, non-identity meaning.
More likely Boi
- A youthful, boyish masculinity fits you better than a more settled, grown one — boy without being a man, rather than a mature butch feel.
- You want to acknowledge the word's specific roots in Black lesbian, queer and hip-hop culture, and you're comfortable with there being no single fixed definition.
- You're using it in a kink or leather context where boi names a role, separate from any claim about your gender.
More likely Butch
- You want the word with the deepest, most documented shared history and community behind it, going back decades.
- Your masculinity feels settled and grown rather than boyish, whatever your age.
- You want continuity with a wide range of butch experience — women, nonbinary people, and transmasculine people alike — under one long-established banner.
When both words are honestly available
- Both describe masculinity built inside queer, often lesbian, communities rather than borrowed directly from straight male culture.
- Neither implies womanhood is being rejected outright — plenty of people using either word are also, comfortably, women.
What people get wrong
Boi is just a cutesy spelling of butch, meaning the same thing.
They have different roots, different feels, and boi carries a specifically Black American and hip-hop lineage that butch doesn't share, plus a non-identity meaning in kink contexts that butch lacks.
There's one clear, agreed definition of what a boi is.
There isn't. Two people who both call themselves bois can mean noticeably different things and both be using the word correctly — it's a much less settled term than butch.
Questions people ask
- Is boi always about gender?
- No. In lesbian and butch communities it usually names a youthful, boyish masculinity, but in leather and kink contexts boi can be a role rather than a statement about gender at all.
- Who uses the word boi?
- Most bois were assigned female at birth, though not all — some are trans men, some are lesbians, some are neither, and the same person may use different framings depending on who's asking and how safe the room is. The word's spelling and much of its use in queer spaces trace back to Black American English and hip-hop, carried in largely by Black lesbian and queer communities.
