"Nish" comes from Anishinaabe, the tribe more widely known as the Ojibwe. "Nish" is used among friends and family, or even a complete stranger (as long as they're a Nish, too). Always used on friendly terms. It could be an insult if used in the wrong way, but why would you want to do that?
"Look at that big Nish! Right over there!" - nish #1
"Howah! He must have a huge nishnob!" - nish #2
"Sha hi!!!!!! You're so sick minded, cousin! Ayaa, but he is sexy..." - nish #3
