The Squnity Dutchman is when you're fooling around with someone and you're about to do it, then somebody walks in the room and interrupts you when you have your shirt halfway off. Then they pretend to look away but really they're still looking at you, thus the squinting. This usually only happens when you're about to bone someone of dutch descent.
