An annoying person who responds to hearing someone else’s experience or problem by immediately telling a similar story about themselves with a much less interesting or boring corresponding story. (Note: The story will be much longer than you could ever imagine or want)
Person: Last summer I went to Thailand and rode on an elephant.
One Downer: Last summer I rode my horse in my backyard while my brother watched. My brother also rode the horse. then we went inside my house and had a sandwich.
