A second cousin that only shares one great grandparent instead of both great grandparents.

Get the Half Second Cousin mug.
1- Parent's half-first-cousin's child.
2- Grandparent's half-sibling's grandchild.
3- Person who, in relation to the other person, has zero parents, zero grandparents and one great-grandparent in common.
My half-second-cousin is a good person.
