octuple-third-cousin
Someone who has no parents, no grandparents, no great-grandparents, and fifteen great-great-grandparents in common with someone else. Like they’re related but barely.
My octuple-third-cousin walked in. He said, ‘We’re related? I didn’t even know you existed.’
My octuple-third-cousin showed up at my house. He didn’t know who I was. He just said, ‘We’re related?’
My octuple-third-cousin sent me a text. He said, ‘We’re related? Why didn’t you tell me?’
