Everyone's name gets a "y" added on it...
Go Mikey
Go Tommy
Go Ralphy
I did this to my friend in a 5k race and he told me never to do that again because he is not gay. Not sure if that makes sense, but its what he said.
I used to run the 3200m indoors (16 laps) and each time I'd go by, a guy on our team would say my last name in a way that emulated a speeding car going by. If this isn't funny, maybe you had to be there.
On a mass bike ride in Mexico, the little kids on the street sides would say "Andele" which reminded me of Speedy Gonzales, but some of them would jump up and down saying "Candy! Candy!" They were more or less begging more than cheering.
