When you combine a Fart with a Burp while Twerking. The words originate as Twerking Furper (Fart-burper). Throw it in a social blender and tell those hyperactive drunk mates to stop being Ferking Twerpers.
Drunk friend: "Bro, the DJ's playing my jam, check these moves!"
You: "Stop embarrassing yourself you Ferking Twerper..."
