HAPPEN: Hold "index fingers" out in front of you, palms up.
Then roll your hands over so they are both facing downward.
Notes:
Often this sign is used to mean the equivalent of the English
phrase, "and then..."
Note: If you do this sign with a "WH-Q" (furrowed eyebrows) facial
expression, it can mean "What happened?!?"
Also see: "What's up?"
