paisan
A loud, sweaty Italian guy who calls you ‘paisan’ like he’s your long-lost cousin from the same village. It means brother but also implies you’re gonna fight someone for him.
"Paisan! You’re my bro! Let’s go beat up that kid over there!"
"I didn’t know you were a paisan until you yelled ‘Mama!’ in my face!"
"You call me paisan one more time and I’ll throw you off the balcony!"
