lay'n trench 

Skiers and snowboarders who are carving turns down a ski hill are known to be "lay'n trench", because of the deep ruts left in the snow.

Dude asks, "Hey man, are ya making pow turns today?"

Bro replies, "No Dude, the snow ain't deep enough out there. I'm gonna go hit the groomers. Today's the day to be out there lay'n trench!"
