What is bail flip? The trend inspired by Virat Kohli, Siraj

Indian pacer Mohammed Siraj, wicketless in the third Test against Australia, was seen engaging in gamesmanship by flipping the bails at Marnus Labuschagne's end. Labuschagne promptly reversed the action. Flipping bails is a cricketing superstition believed to bring luck and wickets, with past examples including Stuart Broad, Virat Kohli, and Nathan Lyon employing the tactic.
