look up any word, like thot:
 
1.
When someone fart's on one's penis.
Your lover is lying face down, you place your hands on there buttocks and with your thumbs you seperate there cheeks. Then placing your erect penis between the spread cheeks, then release the cheeks causing them to clamp down on your penis. Your lover then fart's sending it racing along your shaft.Enjoy your Whistle Dog

An obscure selection on the menu of fast-food mofos A&W. It's like a hot dog, but with more enthusiasm.

When the customer ordered a whistle dog, the clerk cringed as he fished one out of the warmer oven. Those mofos were 42 months old!

3.
A hot dog with bacon and cheese.

Term is somewhat popular in Canada and less so elsewhere. Whistle dogs are available at Canadian A&W as well as many smaller, independently-owned restaurants.
Hot dog! Dad made whistle dogs for dinner!
