Why called "Choppers" ?

[HONKY660]

We use Choppers as a nickname at our chapter. When I have attended conferences many chapters have shirts and stuff that say Choppers, especially for intramurals. We used to call girls that several brothers had "dated" "Chopper Hoppers!"

Haha, I remember the first time I heard that nickname. I was working a water stand during the Kentucky Derby Festival's MiniMarathon for community service, and one of the runners comes by, grabs a cup of Gatorade and yells "Good job, Chops!" He must have thought I was nuts considering the ridiculous face I made as he passed by. Our High Pi was there as well and explained it to us (I'm guessing it was more common at his school).
