Anime / Manga - Anime delinquents, wanting to gangbang you and cutting your arms off.

I can't stop thinking about "What if this was an actual thing" now
I mean imagine it
People walking down the road, suddenly you pass an alley and there's five dudes around you
You prepare your wallet/anus and suddenly they tie your sleeves shut and bail
And it's not just you, this is happening all over town
People start wearing short sleeves everywhere, no matter the weather, to avoid becoming targets
