Origins: hot men employed in staff canteens/cafes. They often appear outside the kitchen's back door, tempting the passing professional ladies like scraps of food being thrown for the local hungry dogs.
Wider use: general term for any hot men.
"Hey, that man-scrap who likes to stare is back at work today, result!"
A person employed to fill the gaps between bricks in apartment buildings, using concrete and a trowel, in order that a building may be painted. A subcontractor with poor sense of timing - 6 am on New Year's day, Saturday mornings at 7, or late at night are his hours of work. Once finished with this job, he uses noisy power tools to further annoy sleepy residents. If it gets really annoying, one should contact Gerrn Shirt Man.
