A uber-potent drink made from the cheapest vodka, coffee liqueur, and irish cream you can find, topped off with way too much half and half (to cover the low-quality booze) and then shaken and served with ice. Not to be confused with a TGI Friday's mudslide.
Guy: I just horked my dutch whistles.

The act of whistling while someone else covers your nose with their mouth, blows air through your nose and it comes out of your mouth and you begin to whistle.
my girlfriend thought it would be funny to cover my nose and blow into my lungs. But what she got instead was a dutch whistle.
