For instance, the object related to cooking is a "dish", when playing it is "sport" or "game", when singing it's a "song".
Which single term would describe the object for the general act of doing something for leisure?
The closest I've got to is a "fun thing". So that I could say "I did a fun thing last weekend" as opposed to "I did work last weekend".
Would anyone like to volunteer a neologism if a term does not exist? Something catchy, please.
