Help me with names? please! 10 points!!?

I really need a theme for my cabin at camp! It needs to start with an "R" because our cabin is Rough House. Past themes include recess rough, royal rough, record rough, and raptor rough. Each person (about 50 of us) need to be able to make a name for ourselves relating to the theme (ex: Princess Peyton etc...) Any suggestions would be VERRYYY appreciated!!! thank you! (10 points for best answer!!)
