Ochies - The fake name you use for your friend so you can tease them

The fake name you use for your friend so you can tease them without getting in trouble.

I call my friend 'Ochie' instead of his real name because it's funny.

My buddy's nickname is Ochie because he's too lazy to remember his real name.

I use 'Ochie' for my brother because it's easier than saying his full name.
