Hello guys! Our #slang word of the day is ”Mug”, which means “a face“. That’s what we’ve found about its origin: "Mug" has been used as a noun to describe the face and as a verb of the word "grimace" since the 17th century. It most likely derives from "mugg," a Scandinavian word for a drinking vessel. In the 17th and 18th centuries, mugs were often decorated with cartoonishly-drawn human faces. This may have led to the use of "mug" as a synonym for an ugly face."
