Shibby is (or was back in the early '90's) a greeting: "What's Happening?", or "What's up?", though it can be also used to say "Seeya!"

Most have it wrong (though I guess the NEW meaning is now more popular, effectively replacing the old one).

All these 'dude where's my car' references are 1) funny and 2) incorrect.
