Jon, Jonny, Jonny P, Jonny Effin' P, JP
as you can tell my friends are very original. Shortened first name, and last initial.
Other than that, "Radio Shack" by friends I went to grad school with as I used to work there, "Moses" due to a hilarious moving story (I don't have long hair nor a beard) and "the Greatest" in junior hockey circles.
Other than that . . . can't say really I have any.
People here call me "Maritime" "Scout" "Q-Scout" "Q" and "MQS" but does that really count?
