I'm joeking

You say this phrase when you say something and want to clarify that you didn't mean it literally and was meant to be a humorous retort. But in reality, you're never joeking. Mnmrocks is joeking.

Here's an example of the word being used:

Random dude: Nah I'm joeking amigo, don't take it seriously
Galaxy brain: You're not joeking, mnmrock is joeking.
