a sister-cousin is when your baby's daddy has a child with your sister-- your baby and her baby are sister-cousins.

It's not my cousin, it's my sister's cousin so we can fuck

When me and my sisters cousin are scrawgin in the back seat it's legal since she ain't my cousin, she's my sister's cousin

Your female cousin whom you are so close with that your relationship reminds you of a loving pair of sisters.

That’s not just my cousin. That is my sister-cousin.
