P. LePew asks: “My friend told me she likes to eat Mexican food and then go ‘crop dusting’ at Wal-Mart. What does this mean?”

 Ask Red says: It means you need a better class of friends. “Crop dusting” is another way to say you “squeak” when you walk, but it is not the sound that is disturbing; rather, it is the essence that follows. While your friend seems a bit boorish, she is also reckless by crop dusting at a Wal-Mart for 99 percent of that store’s clientele is likely ready to return fire with the push of a sphincter. Also, a typical Wal-Mart customer smells so badly they might not even notice the foul prank. A true crop dusting artist would reserve her outbursts for a more refined place like Nordstrom’s or Sax. Of course, there everyone has their noses so high in the air they might not detect the folly.
