1. Georgetown University mascot. The official explanation holds that there was a baseball team at Georgetown called the "Stonewalls". It is suggested that a student, applying Greek and Latin, dubbed the team the hoia saxa-- hoia is the Greek neuter plural for "what" or "what a", while saxa is the Latin neuter plural for "rock". Substituting a "y" for an "i"; "hoya saxa" literally means "what rocks". Now, a Hoya takes the form of a Bulldog, but students still cheer "Hoya Saxa" at games.
2. A student or faculty member from the greatest university in the history of universities.
"Georgetown Hoyas are the best students around"
