When your jeans absorb salt through snow found in parking lots & the like and create a white lines at the cuffs of one's jeans. This occurs after every winter snow fall in northern climates as salt from the roads gets all over your feet and soaks your jeans. The rings creep up your jeans from the bottom up and create a white line ring around them.
"Why aren't you going out tonight?" "I have no clean jeans and need to do laundry because all of them have salt legs."
