I'm no mathemagician, but I think that might even be sad cubed.
There's no reason to be sad on Saturdays! haha. It can still happen, sure, but I think the tag is definitely more fitting for Sunday or Monday. I like a lot of really, really sad songs, so I could probably have fun with that, bumming everyone out along the way.
#PartySaturday seems like a good idea to me as long as no one posts Andrew WK.
LOL 🤣🤣🤣
