jack knife barber
A guy who shaves the top of your head with a rusty knife while you're still crying from the last one. He's like a sadistic理发师 with a vendetta.
My aunt had a jack knife barber and now she looks like a raccoon that lost a bet.
He did my brother's head and now it looks like a pizza that got stepped on.
That barber didn't just cut his hair, he made him cry.
