When people form a horizontal single file line in the hallway, and nobody can get past.
They move so slowly I want to beat them all with an 18 wheeler.
Then when you try to squeeze by in the almost nonexistant space between the wall and the edge of the starfish line, if you do so much as tap them accidentally the throw a screaming fit, but they expect everyone to get the forget put of their way.
A LOT of black girls do this at my school.
