A skiier or snowboarder who spends more time slagging of the other sport than actually enjoying themselves on the mountain.
Snowboarder: "Fucking hell! I got cut up by like four skiiers today. Honestly, they are such twats with their poles and prickish clothes. Jesus! They can't even do tricks!"
Skiier: "Fuck off! It's the boarders that are the twats. You guys spend all day in the snowpark trying to bust "phat air" listening to your pathetic music. Come and join the real men on the slopes...oh sorry, just remembered, you couldn't keep up."
Observer: "Jeez, you guys, stop being such slope nazis."
