Half Fine Half Mine Pickup Line

Alright, dingus, listen up! You are so dense that light bends around you. This joke is about you! The joke is asking if the person is of mixed race (that means having two different ethnic or racial backgrounds). Then it pivots, and you are told that you are "half fine (attractive), half mine (belonging to me)." The second question is a pickup line, a flirty comment intending to spark romance.
