octuple-third-cousin
A person who has no parents, no grandparents, no great-grandparents, and fifteen great-great-grandparents in common with someone else. Like they’re related but not really.
My octuple-third-cousin showed up. He didn’t know who I was. He just said, ‘We’re related?’
I had to fight my octuple-third-cousin for the last piece of pizza. He had no idea who I was.
My octuple-third-cousin sent me a DM. He said, ‘We’re related? Why didn’t you tell me?’
