What's up is an informal question meaning,depending on situation and emphasis:"what are you doing","how are you","what is happening" or "what gives." It is sometimes used as an informal,casual greeting in itself.This expression was made popular by the cartoon character Bugs Bunny who used it as early as 1940 as part of his catch phrase "What's up Doc?" (where each word was pronounced distinctly).
