  • There are a lot of definitions for this word. I just happened to notice that two are missing:

    Treat: What the termite guy does when he comes to your house the first time to discourage termites from eating your home. Involves spraying a liquid substance around the foundation of your house.

    Treat: What the termite guy does when he comes to your house the second time to discourage you from calling him again. Involves spraying several rooms of your home with what ultimately will look like machine gun fire, thus causing said rooms to resemble any of a number of scences from The Godfather -- pick your favorite: the tollbooth, the revolving door, the elevator, the barber shop, the massage parlor, etc..(OR, the car in the last scene from Bonnie & Clyde).

    You're welcome.
