To play a joke without the other person knowing about it. Doesn't always have to mean a joke played on by another person but can also refer to any crappy situation in general.

Yoking is different than pranking in the way that it is like a prank, except pranking depends more on the actions of the other person and physical encounters, while yoking is more of like a joke.
Example #1:

John: "Where the hell is my bag?"
Bill: "I don't know dude, I think Sam hid it somewhere."

Example #2:

Jane: "Where is Sam with my cell phone?"
Jill: "I think he brought it with him on his trip to New York"
Jane: "You have to be yoking me"
