Space on the kite field is a high commodity sometimes. At the larger events, there is sometimes a group of folks that wake up super early to go stake their claim on the kite field before everyone else. Jokingly, this group is named the prostate club, as it is perhaps because of this troublesome body part that they are awake early enough to stake out their claim.
Used in a sentence:
Eight am, and already the Prostate Club has taken up the best parking and the best field.
