Since most of the guys I ride with have modern fuelies, v-rods, etc..., and I had the oldest bike in the group that can actually still do the potato potato potato, very slowly as well, my 21 year old Springer got named "Cough-a-long" and it stuck.
I actually was kind of proud of that because I always felt my bike was more of what Harley stood for than the modern bikes... and it can still to the "potato"!
The new bike doesn't have a nickname yet because I don't get to pick it up 'til Friday @ noon, it will get a moniker one day over some little event and that'll be that.
