Punch'im in the Tan!

The dream started out depressingly normal, working in cubeland again, answering the phone for some sort of help desk application help line. Suddenly one of my coworkers decided to challenge the statement of another that he had a bald spot starting on the back of his head "like him" (said while pointing over the cube wall at me.

Balding guy and the rest of his friends headed over to the photo copier, so they could hold him upside down on top of the copier.

"Don't you people have phones?" asked one of the cube-women as they struggled with their load at the copier.

Suddenly they were all shouting, so loud it woke me up "Punch'im, in the tan."

I still have no idea what that means.
