What is Dryer Liar?
1.
A person who when using a public restroom that has electric hand dryers rather than paper towels, who doesn't wash their hands but pushes the button on the dryer before leaving, so that when they open the door, others may hear it running and just assume that they washed their hands.
I heard the hand dryer when John walked out, but he's not fooling me, he's just a
dryer liar .
