In my high school (Massachusetts, USA), almost all the students went by their last names, or something related to their last names. Ashley Milford was Milf, Samantha St. Paul was Saint Paul, Ryan Leonard was Lenny, Kevin Doo was Kevin Doo, for example. I'm still my surname in my head.

I learned later that we had a reputation for being a jock school though, because we all had to play a sport each semester.
