Explanation

  • A very informal greeting asking what someone is doing or what's new.
  • Can also be used to inquire about a specific situation (What's up with that noise?).
  • Often doesn't require a literal answer; Not much is a common reply.

Origin

  • Popularized in the mid-20th century, possibly influenced by earlier phrases like What's the time? or simply What is up?.
  • Gained widespread use through American culture, particularly associated with youth and casual communication.
  • The cartoon character Bugs Bunny's catchphrase What's up, Doc? (starting 1940) significantly boosted its popularity.

Alternatives

Slang/Informal:

  • Sup? / Wassup? / Wazzup? (Common shortenings/variations)
  • What's good? (Urban/AAVE influence, asks what's happening or positive news)
  • What it do? (Urban/AAVE slang)
  • What's crackin'? / What's crackalackin'? (Playful, informal slang)

Milder/Standard:

  • What's new?
  • How's it going?
  • How are you?

Situational Appropriateness

  • Very informal.
  • Best used with friends, peers, and in relaxed social environments.
  • Avoid in formal business settings, job interviews, or when addressing authority figures or elders unless you have a very familiar relationship.

Misunderstanding Warnings

  • Non-native speakers might try to give a literal answer about what is physically up.
  • They might also be confused by the common Not much response, wondering why someone would ask if they didn't want an answer. Explain it's often a ritual greeting like How are you?.

Examples

  • Hey man, what's up?
  • What's up? You look worried.
