Boi can be used in any occasion. It can be like saying “seriously” or literally anytime. It means everything. One example is “boi what the hell boi”. I say boi way to much. saying boi is not annoying it’s annoying if you don’t say it.
A way gay men spell boi. Originally comes from XY magazine. Recently misappropriated by the straightcommunity like they do with all other things gays do first.
