I would say atleast 80% of the time because there are people who are legitimately only saying things as a joke. But people (friends and family) will say the most absurd thing about you or play the worst prank on you, and say: “it was just a joke, it was just a prank.” Knowing good and well it wasn’t something to joke about. And here’s the other thing, jokes are supposed to be funny. Most people don’t get the concept of a joke. It’s not always that I don’t have a sense of humor. You just don’t have humor AT ALL.
That’s known as “Schrödinger’s asshole”. It’s both a joke and an insult at the same time, who knows, until they see the reaction!
