Who is the patron saint of cheerleading?

As far as I can determine, there is no special patron saint of cheerleaders. However, there are a number of other female saints who could help you: St. Lucy, St. Agnes, St. Philomena, St. Maria Goretti, for example. Even St. Teresa of Avila would be a good choice. During her teenage years she was quite rebellious and preferred boys, fine clothes and socializing to a religious life.
