Someone that, in some aspects of your friendship with him, is a big brother (e.g. Pays you out and jokes around but knows when to just stop and listen) but in other aspects, an uncle (e.g. Your mum or dad has also adopted him as their brother.....hm). You really can't decide so he just becomes both, smooshed together :)
Thanks for listening Broncle, you're the best!
