Why do so many Brazilian players ign end in zin?

Artzin, mazin, cauanzin, snwzin, etc. What does it mean?

I could be wrong but its sort of like a word for cute (as in the type you would think a baby or dog are)

nepotizm

It's a diminutive, like saying Little [name]

because itzin their veins

zin is like little

its a diminutive like ito in Spanish (perro -> dog, perrito -> puppy)

cauanzin -> Lil Cauan
