bruv
Casual sibling address
Bruv is British slang for brother, used as a casual term of address among friends or acquaintances, particularly in London and urban areas.
Like its American counterpart bro, it signals familiarity and solidarity without implying actual family relation.
Alright bruv, you coming to the match?
The term carries working-class and multicultural urban associations and appears frequently in British youth culture and grime music.
