Penalty box refers to the party starting in say a 3x2 or 3x3 square at the start of battle all adjacent to one another. In many modules with area or burst creatures, this can mean much of the party is massacred before moving if the creatures get surprise.
When we do this in 4E the 40K part of my brain kicks in and I have visions of flamer or 3" templates being dropped on the lot of us.
