Machae - A word for your brother-in-law, but also used to call your b

A word for your brother-in-law, but also used to call your best friend. It’s like calling them ‘buddy’ but with more sass.

I called my brother-in-law a macha. He laughed and said I was a moron.

My best friend calls me macha. I think he’s being extra today.

I said ‘Hey macha’ to my neighbor. He thought I was trying to flirt.
