Incesting

The act of a family member totally making moves on another family member.

Adrianna: "So my cousin messaged me on Facebook, and he was all like, 'hey baby, good morning, i love you' and I got scared cuz I thought he was incesting me up so I signed out. Then I realized that his fiance has the same name as me."
Brandon: "lol awkward"
