Whan some how your uncle become's also your brother and you are unsure of what to actually call him when introducing him to other's.
When my mom took in my Uncle who was only 4 year's older then me and 2 year's older then my sister, but was 18 year's younger then my mom, he was my Uncle who became my Brother. He was now my Bruncle!
Hey, check out Lana's bruncle. He's pretty cool how he is alway's there for her, just like a brother would be.
When you consider your uncle to be more of a brother then an uncle, he become's your bruncle... Yipee!
