Nicknames for a “big brother”?

[Babypinklittle1]

So my Daddy and I just started dating someone who acts as my “big brother”. Big brother is kinda long for a nickname, and I can’t figure out a way to shorten brother to a way I like. So I was wondering if you guys had any nickname suggestions! He’s not a little if that influences your brainstorming lol

Bro-Bro

I've legit heard kids use this so it might be cute.

Bubby or Bubba, has a nice ring to it.

the same thing happened to me when I was little but it was with my actual brother and his friend I would just say his name

I think the best nicknames kind of form on their own while you do stuff together. So, just use his name for while you give it some time to develop naturally, try out a few things and see what sticks.

 

Have fun!

Maybe you could use a diminutive based off his real name? My uncle was a teenager when I was born and I always called him "Willie" instead of Will or William.

My little sister had some cute names for me growing up.  I can't remember them all but I recall some of her favorites like dum-dum, stupid-head, shit for brains, stuff like that.  Good luck!

I call my big brother bru-bru

i call my brother "yakko" from the animaniacs! personalization is important in nickname, in my opinion.

This topic has a bunch of alternatives to "daddy".  I know you are looking for something different but there are a lot of creative ideas in here: https://www.ddlgforum.com/topic/17009-alternative-names-to-daddy/

Bobo

Bilbo Baggins. o_o This is forever his nickname. Good 'ol Bilbo Baggins reduced to... Bobo.

 

Agree with others in that nicknames come naturally and could be based off of their actual name (as most nicknames are?).

You could also look up endearing terms or how to say (big) brother in other languages. ^^
