hoondune
Another word for kook, or poser, but only a woman can be a hoondune. Hoondunes are also known for being promiscuous, mainly attracted to someone in the professional sports category, also known as a pro ho. Hoondunes are known to be stuck up rich girls who spend more money and time to look the part, rather than taking the time to get better at the sport that they latch onto.
Maybe if that "hoondune" Shelby actually snowboarded as much as she talks about it, she might be able to actually ride down the mountain without looking like an idiot.
