A phrase often heard in electrical engineering digital electronics classes. Since most engineering professors are foreign, they cannot pronounce Flip Flop properly.
Prof: For Q on the frip frop
Student 1: Did he just say fuck you on the frip frop?
Typically uttered via chinese accents, means in english "flip flop", as in a sandle or a shower shoes.
Wang told me he had to borrow my frip frop because he broke on of his during karate.
