hi

a form of meeting someone as a conversation starter that makes mom or dad stay in the store an hour longer because they see someone they know and makes the kid's life 100 times more miserable

Dad-"hey is that Joe?"
Kid-"don't do it dad."
Dad-"too bad. I have to tell him about the 3 week vacation I just went on. It won't take to long."
Kid-"AAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!"
