When a celebrity appears in a photo or video taken with a regular person and the person is not aware of it. Its a form of photo bombing.
The dude doesn’t know Tom hanks, never met him never will!! Tom was sitting at a bar when he noticed this guy passed out. He went over and noticed the guy’s smart phone on the table. So he shot off a few pics and put the phone in the guys pocket!! Imagine waking up the next day and checking your phone!
