A grey shirt is another term for a school student of grade 7-10. Names such as; absolute Panzy, honourless coward and godless heathen, are synonymous with the grey shirt. The only thing more noticeable than a Grey Shirt's pungent stench is the extremely dangerous speed at which they sprint on the pavement, disrupting the local population and making them wonder if they're trying to be a disappointment to their parents. While known to often approach AND TALK to human beings about their lost troglodytic instruments (handballs and hats), know that behind the fragile husk that is their fictitious confidence, is an underdeveloped homunculus and as such; can be easily transported and placed inside a bin where they belong.
Apologise for approaching me and my colleagues, Grey Shirt.
