Cuck Fu is what happens when two dudes feel obligated to engage in physical combat over a woman, usually in a sexual context.
Person A: Hey, did you hear Tyler and Chad are fighting over Becky again?

Person B: Yeah, it went down the other night. It's shaping up to be the Cuck Fu title fight of the century.
