A family wiper is a person who hooks up with every single person or child within the same family, making all the siblings spit- sisters/brothers.
Brother 1: I just hooked up with Ashlynn
Brother 2: wait I did that yesterday...
Sister: I just did that an hour ago
Brother 1: I guess she's a family wiper.
