Straddle a girl's face while she lies on her back. Spread out your nut sack as far as it can go and place it over her mouth and nose creating a old western bandanna with your sack. You can even make her say, "High Ho Silver....AWAY!" while she has the bandanna over her face.
Hey Lucy, come on over to my place tonight so we can play Cowboys and Indians. You can try on my Indiana Bandanna!
