Hot Tuna Sandwich 

Highly sought after by certain ladies, this delicacy is another term for the spitroast, where two gentlemen entertain one lady at the same time. Usually orally and vaginally, but other configurations are possible. The lady is obviously the "Tuna" in the aforementioned sandwich.

"My twin brother rang me and told me that his new girlfriend was hot for a threesome, but I wasn't sure until she came on the line and insisted on it. So I ended up serving up a hot tuna sandwich that afternoon."

Tuna Sandwich 

For centuries the true definition of Tuna Sandwich has been lost until recently. Explorers discovered hyroglyphics covering the walls of the long lost pyramid of Barramundas. The only fish king to be mummified. The pictures adorning the walls were unwashed naked women with exotic vaginal adornments - that of the 99 cent tin of Tuna. As the explorers searched further up the walls they noticed that some of the unwashed women were having a snack on the said vaginal adornment, encasing it in 2 slices of bread.....

Girl one - I'm really hungry
Girl two - Me too
Girl one - I have a tuna sandwich
Girl two - Me too
Girl one - Wanna bite of mine?
Girl two - Only if you can take a bite of mine too
Girl one - Mmm love that tangy mayo
Girl two - what mayo?
