HAPPY HUMP DAY!😉👋 What does HAPPY HUMP DAY mean? Professionals and students wish each other happy hump day as congratulations for making it through the beginning of the week and as encouragement to make it through the second half. The phrase is also often used in the media to headline content published on Wednesday. Wednesday first came to be known as hump day since at least the 1950s. The expression figures Wednesday, the middle of the workweek, as the hump people get over to coast into the weekend. Throughout the 20th century, Wednesday was especially referred to as hump day in an effort to liven up the drudgery of the workweek. Coworkers may wish one another Happy Hump Day! in a lighthearted or ironic acknowledgment that day-to-day work can be a drag. Evidence for the phrase dates back to at least the 1980s.
