The london trick beef? a.k.a 5th Floor Fixie Crew Implosion

so an altercation/interaction resulting in a black eye was not one involving violence?

you've obviously misunderstood.
as i said, this is evidently an act of violence, just, because she thinks that it wasn't necessarily an 'ambush' and just a talk between two guys that got out of hand, she thinks that it isn't exactly what it's being portrayed to be.
