Singular. Stunt Crew - Plural. A pretty beast dude cheerleader who is part of the cheerleading squad. They do wicked awesome stunts like toss to hands and tumbling. They also assist the other cheerleaders with the stunts by backing or sidebasing stunts like libs, basket tosses, and assist with cradles.
Dude, look at that dude cheerleader, he must be part of the stunt crew!
Did you see that awesome tumbling pass that stunt man did? Dang, i wish i could do that! I guess it is true: if cheerleading was easy, it would be called football!
