A mastermind of mysterium and opulence. Often claimed as a ghost, no one knows the real identity of Gustin. Often used as slang of the University of Central Missouri's Ellis residence hall.
"Did you hear the airhorn on the fourth floor of Ellis?" "Yeah it must've been Gustin!"
"All the whiteboards are covered with the name 'Gustin' and I'm super confused."
"Gustin is so based."
