Brosin 

A male cousin who is more like a brother. Brosins and cuzisters grew up together supporting one another through thick and thin. They understand the crazy family they were born into, they share inside jokes, they are there for each other and they choose to hang out with one another because they want to. They are strong, goodhearted with an unbreakable bond, after all, they get it from their mamas.

My brosin and I are cousins by blood and siblings by choice.

Brosin 

A half-brother who is also your cousin. The male offspring resulting when your sperm donor also impregnated your mom's sister. The male version of a couster.

I used to get along really well with my cousin Jake, until I found out we had the same dad. Now he's my brosin, and it's kinda awkward.
