I'm in my 4th serious FM save atm, and in every single one I've found bunch of regens with the same "nicknames" - Fusca, Fuska and Xaropinho. They're all Brazilians and I don't have their league or their players loaded. Few of them are playing for some massive clubs like Bayern, Tottenham and Porto. In my previous save with East Stirlingshire, I had 2 badass Xaropinhos, I think one was in Liverpool and other one in Real Madrid. I believe these nicknames are nowhere near that often in RL. Search it (if you're in 2015+ year or so) you'll see what I mean.
