When you are wearing short shorts and a long T-shirt and a stupid salesclerk doesn’t remove the security tag from the CD you bought and you get stopped by store security who refuses to let you go because he’s convinced you are a shoplifter, mean is peeing right on the floor of the CD store in protest.
When you are stepping off the sidewalk to cross the street at the light and some young idiot pulls their car in right beside you and starts yelling at a friend across the street, mean is keeping them there for 10 minutes by doing a little in-and-out dance, attempting the cross the street and going back.
