(Most of the time this term is used incorrectly as a fashionable way to spell "boy". The actual (true)
definition is associated with
LGBT and Bdsm communities.)
Boi (plural: bois) is slang within
LGBT and butch and femme communities for a person's sexual or gender identities.
Boi may also refer to someone assigned female at birth, who generally does not identify as, or only partially identifies as feminine, female, a
girl, or a woman. Some bois are trans or intersex
people.9 Some "bois" identify as one or more of these, but they almost always identify as lesbians, dykes, or queer. Many trans bois are also genderqueer/nonbinary (in itself a trans/transgender group), or might identify as cis persons or trans
men, and yet practice genderfuck in which they do not fit in either masculine or feminine binary gender presentation.
(BDSM, especially in roleplay) A male bottom (i.e. submissive partner), defined not by
junior age, but by his obedient role, especially when that implies him being subject to spanking and/or other punishment by the dominant "top".
