Oh. I see.
Looked like two sikh lads from my school going at it.
(I say 'sikh' not as a reflection on adult sikhs, because every grown-up sikh I've met has been polite and charming. But their teenage boys are sometimes quite aggressive, from my school experience, and think that a £2 bangle will act as a knuckle duster, so get into fights and approach a fight by throwing wild hooks in the hope of landing anything.)
