finally someone actually gets the name of the trick right, cork 7. jonny mosely is just a dumbass (i know he's better than me) and decided to call it a 'dinner roll.'
The 'Dinner Roll' was just a joke between him and his friends, it's people like you who take it too seriously that create skiing drama. Let's leave the drama out of it. You like to do switch 360's, he likes to do rodeo 7 japan's, and sometimes he kicks it up to a 9. Plain and simple.
