Adding to the fun and mirth this thread allows...each of the riders, often have a nickname.
Valentino Rossi - aka The Doctor (Il Dottore)
Fabio Quartararo - El Diablo (The Devil) or El Pascal
Maverick Vinales - Top Gun for obvious reasons
Miguel Oliveira - Einstein (since he likes to stick his tongue out like the original AE)
Marc Marquez - Baby Alien, or as I like to call him the King of COTA (Austin race track), I"m sure others call him Beelzebub or other more derogatory terms too.
Francesco in Italian, Pecco for short is just like Francisco in Spanish, with Paco for short...quite similar
Amongst friends, we call each other by last names as a term of endearment, I see some folks like to call each other by their initials...although that's a bit more of a southern style.
