What is a weenus?

The term "weenus" is often used colloquially to refer to the loose skin on the elbow, specifically the skin that wrinkles when the elbow is bent. While not a medically recognized term, the weenus is simply a fold of skin on the outer part of the elbow that allows for flexibility and movement. It is not a separate body part or structure. Despite its humorous name, the weenus serves an important function in allowing the elbow joint to bend and flex.
