look up any word, like columbusing:
 
1.
Having a cousin who is also your best friend. Fruz can also be an appropriate shortened version of the word, and used in casual conversation.
I am so stoked I get to hang out with my fruzin today

Hey fruz, can we talk about this?

Cousins, who are more than just cousins but are also friends.
I'm so glad that you are not just my cousin, you are my friend, my fruzin!

3.
Cousins who are closer than just being related, but are actually good friends (cousin and friend put together).
Evan and Alex are more than just cousins, they are fruzins!

Evex are the best fruzins ever, they know every thing about each other!
