I only heard this once, but it was enough:
"I can ski fine. I just can't stop or turn."
Teenager to tentative buddy:
"This is easy. You can ski this."
Any number of 40ish males standing atop any number of bump runs anywhere in the world:
"I'm getting too old to ski this."
"My feet are cold. I need another pair of socks."
"I didn't know you could get sunburned like this in January."
"It's really hard to ski in this powder. The grooming here really sucks."
"My new (substitute name of locally popular Giant Skis here) are the best for everything: deep powder, crud, bumps, crust, groom, hardpack, gates. I can rip anything on these!"
"You should carve everywhere. If you don't carve, you're not really skiing."
"I tried those new shaped skis. They were too unstable."
"I rode (substitute name of local Fearsome Run)!!!" (This is often said by a snowboarder who just sideslipped the whole thing without managing a single turn.)
Typical instructions by friends/family members:
"Lean forward!" (The person doing the shouting, of course, bends forward sharply at the waist, while his calves remain firmly planted against the backs of his boot cuffs.)
"Dig your edges in!" (Shouted by someone whose wife/husband/child is careening out of control down or across the hill.)
"Use your sticks!" (Meaning ski poles, presumably. For what, I'm not sure. Often no further instruction about what to do with the "sticks" is provided.)
"You can't turn sharp enough if you don't hop." (While it may be true in some situations, this assertion is often made while standing in the middle of a blue groomer.)
