The make of trousers worn by chavs or extremely unfashionable men or women, who use their expired McDonald's card to buy a cheese burger who everyone knows is for pussy's and low life's
A general term for one who participates in either track and field or cross country. They are often runners but may include jumpers and throwers. Trackies are part of a very close knit community and are often considered slightly cultish. They enjoy haning out in large groups, dating each other, playing games like CTF, Ultimate, and Red Rover, and of course running. Trackies and drama geek do not mix well.
trackie-daks are the bottom half of the tracksuit, not the whole. the whole tracksuit is the trackie; the pants are the trackie-daks. but Random's example is unsurpassable :)
