paesano
A paesano is like a friend but also a short-tempered maniac. They might just punch you for no reason.
My friend said, 'You a paesano or you just angry and short?'
At the gym, the guy yelled, 'You a paesano or you just here to take my weights?'
My brother said, 'You act like a paesano, you punch people for no reason.'
