Screwing with Reality

Someone is lying to another person in a very sarcastic way. Usually, it is obvious that the other person is lying.

Hey man, I heard that you are making out with my girlfriend. That's not cool!
Noooooooo I would never do that dude!
Man, are you screwing with reality?

Screwing with Reality

When someone tries to deceive or mislead another person with a sarcastic lie, the attempt is so obvious or poorly executed that the other person immediately recognizes it and calls them out on their nonsense.

Alex: "Yeah, sure, I totally met Beyoncé at the grocery store last night."

Jamie: "Right, because Beyoncé does her own grocery shopping. Stop screwing with reality, Alex."
