The term 'overdone but amusing' can be summarized by the word 'CAMPY, ' which is defined as an exaggerated and self-conscious style of behavior or performance that is intended to be humorous. This term is often used to describe films, television shows, and other forms of entertainment that are deliberately over-the-top and often contain elements of parody or satire. CAMPY performances often rely on exaggerated facial expressions, gestures, and dialogue to create a sense of humor.
