What would be the correct title for your mother's cousin's son?

Question

I have a friend who's technically related to me, but not closely. He's going to be coming over my house today, and we're going to have a good time. I just don't know how to address him by, besides John. Is there any specific title to him? I thought since my mom's aunt would be my great-aunt, that my mom's cousin would be my great-cousin, so my mom's cousin's son would be great-second-cousin. But that sounds pretty ridiculous. Any help?

Answer 1

He is your second cousin, as you share great grandparents.

He is your mother's first cousin once removed. Your mother's cousin is also your first cousin once removed. A first cousin once removed is either your parent's cousin, or your cousin's child.

Answer 2

Stranger!

Answer 3

He would be your second cousin. If your mom were asking this question he would be her cousin once removed.
