Frienuncle 

This is a mix of friend + uncle. If you have a friend who is practically a brother/sister to you, their kid can call you "frienuncle," Pronounced "Fren-uncle."

My friend just had their baby; I am its frienuncle.

Frienuddles 

1. When you cuddle with your friend
2. A way to enforce to people that you and someone are strictly friends even though you do some weird shit together.

There is nothing wrong or sexual about Frienuddling with your friend

Frienuddles Was a word randomly made by my friend when texting me
