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.
I'm hanging out with a bunch of trackies later, we're gonna play some ultimate.
