To call somebodys name and then turn or cover your head and not saying anything. The person will yell what and then walk away clueless. its funny. U can also say something like excuse me, or u with the purse. Or be like yo asshole. There are endless possibilites. The person u are rubbernecking will be embarrassed and will have no idea what happened.

John: (hides and says nothing)
Ashley: o whatever it must be me (walks away clueless)
