Used to describe beating someone up in reference to bang being a slang term for sex. The implication being the pain will be equal to rape or some shiz like that. Often used by 12-year-olds on the playground. (May be exclusive to England/the UK but idk)

12yo(v2): nah m8 u weak af. I don't even have a solo kill, bruv. Imma make u ded lmfao.
