air lick
When you are eating with your dog on your lap, and he tries to taste the food just as you are about to eat it, but you pull away and say, "no", so that he can't. Then he licks the air to try and taste what you are eating.
Wilma: Barney tried to eat a piece of my watermelon while sitting on my lap, but I moved away so that he couldn't eat it.
Alfreda: Then he air licked to try and taste your watermelon.
Wilma: Air lick, I like that!
Alfreda: Then he air licked to try and taste your watermelon.
Wilma: Air lick, I like that!
