Stretch
When I first started playing APA (some 10+ years ago) I had a very awkward stance. My left arm (I'm right handed) was no where near straight so when I got over a shot, I my head was way too close to the cue ball and everything was way out of line. Rather than wasting time outs, my team mates would simply yell out "come on Stretch, lets go, you can make it Stretch" thus reminding me to get up and re set up with my left armed stretched out.
My pool skills have since improved a little, and no one has called me stretch in a long time. But it was a cool nick name while it lasted.
