What is thunder buddy meaning?

"Thunder buddy" is a term that refers to someone who is there to keep you company during a storm, typically thunderstorms or lightning storms. The concept was popularized by the 2012 comedy film "Ted," in which the title character, a talking teddy bear, becomes the thunder buddy of his human companion, John. The idea is to provide a source of comfort and reassurance during scary or unsettling weather, when the loud thunderclaps or bright flashes of lightning can be distressing to some people.
