Will, being a guy, liked to comment on the lovely ladies who came to buy plants.
One day an older regular customer he often mentioned came in to the nursery and Will popped his head in the door to say that she was here. I sauntered over to the window to see who had caught his interest. She was pretty far away and had her back turned to me, so Will commented on the quality of her ass, which appeared okay to me. As I went back to my desk, Will said, "Man, she's a total GILF." I was so incredulous that I had to confirm the statement, "You mean, grandma you'd like to fuck?" Will just looked at me with a matter-of-fact innocent and confused face, and earnestly said, "Yeah." Jay and I just burst out laughing. That was the first, and so far, the last time I ever heard anyone use the term GILF.
