Reality seldom matches this fanciful portrayal of the work week, but hump day memes still persist as a sort of relief valve. The phrase imagines the work week as a hard climb to the middle of the week, after which it's all downhill. Hump day memes refer to hump day, otherwise known as Wednesday, which falls right in the middle of the traditional five day work week.
Glad it's not still Tuesday, but bummed it not yet Thursday. We may all be stuck on a treadmill that's slowly wearing down, but when hump day rolls around, it's time for dreams of staying up late and sleeping in with no repercussions. It marks the official point of no return between last weekend and next weekend when that Friday finish line finally comes into view.
