Snake every Jerry you can to assert your dominance. Cut right in front of them, if they hit you then they are in the wrong because you were downhill from them. By the time they realize what happened all they will see is the spray coming off of your skis and a brief glimpse of what you look like as you dodge in and out of all the other Jerrys on your way to the lift line.
Also, talking mad shit to fathers in front of their families in the lift line not only garners respect, but also strikes fear in the hearts of any Jerry that witnesses the conversation.
