Green Polo Friday is a term to describe the habit of insecure, ill-experienced co-workers attempting to strengthen their morale and unite through matching apparel. Interestingly enough, in the act of attempting to become more formidable as a group, the Green Polo's typically choose to represent themselves with the very color associated with employees who are "inexperienced" or "new".
-"Did you see all the rookies in the break room??"
-"Yeah, looks like it's another Green Polo Friday..."
-"Boss, you gotta do something about these Green Polo's... It's mayhem out here."
-"Hang in there. As long as their collars aren't popped, we're OK... Once that happens, then we're in trouble."
