A hot dog and a slice of Velveta in a bun and covered with Manwich and Heinz 57 Sauce.
I told my girlfriend to make me a sandwich, but she didn't have any bread. So instead, she made me a Man-Dog.
A game played by the British Army where one man drops his trousers and spreads his ass checks while the other places his cock length wise between his mate's ass checks. The man who spread his ass cheeks was the bun and the man who placed his cock between the ass checks was the hotdog or man-dog. The Brit soldiers tell soldiers of other nations that the game of man-dog is "totally not gay and you just don't understand because you are US/Canadian/Aussie etc".
