The word "zoeira", from Brazilian Portuguese

The informal Brazilian Portuguese word or slang "zoeira" (noun) is used when somebody wants to kid with others. The verb is "zoar". In this picture we can see Einstein saying something like: "Waiting for the jokes begin" and this picture is used to indicate you are waiting for funny coments about a post on Facebook. Brazilians are always joking or kidding.
Is it this way in your country?
