The hottest old guy in the world who sounds like a woman. He loves to wear spandex and do squats. He's kind of perverted and likes to hide inside school cafeteria trashcans.
Person: Hey GertFibbz what are you doing?

GertFibbz: I'm doing some bun work in my blue spandex!

Other Person: Wow he's really old and sounds womanly, he must be GertFibbz.
