Your brother-in-law is the guy married to your sister. His brother is not your brother-in-law, unless she’s married to both of them. 😄

Well I thought my husband’s brothers were my brother in laws. And I had 2 of those. My sister’s husband made a third one. Isn’t that what we said? You got my head a spinning again. LOL
What the heck we always called all our extended family in-laws. Standing joke was you are either an in-law or an out-law. And all relatives were in.
Yes, your husband’s brothers are your brothers-in-law. But we were talking about a brother-in-law’s brother, which can only happen with the person married to your sister. So, the brother of your sister’s husband is just “extended family.”
A friend back in college was telling a story and he said something about his "aunt's husband." I stopped him and said, "Why don't you call him your uncle?"
He looked at me like I had just said there are 52 states and said, "No. An uncle is the brother of your mother or father."
I felt rather foolish at that moment and remind silent...vowing privately to continue calling all my aunt's husbands "uncle."
