When someone asks you to fiddle their Faddle, they mean that they want you to grab their Faddle and fiddle it. If you still don't get it, it means to jack them off.

It could also just be said after something unexpected happens.
Definition 1: "Hey gurl. Why dont you come over to my house and fiddle my Faddle?"

Definition 2: "Well fiddle me Faddle! I did NOT see that coming!"
