Term used to describe the creative yet unrealistic science in many science fiction films, such as Timecop. This can involve altering history, or a person traveling back in time and touching their younger self, thereby destroying both the past and present versions of themselves because matter cannot occupy the same place at the same time.
Person 1: "Timecop is such a good movie!"

Person 2: "Yeah, it's good even though they use punk science to explain their time travel theories."

Person 1: "Punk science?"

Person 2: "Yeah, that movie is so full of scientific inconsistencies it isn't funny!"

Person 1: "It's still a good movie, though!"

Person 2: "Agreed!"
