Idaho Spud Fuck 

A deviant sexual practice. While a man is having vaginal intercourse with a woman, he inserts one or both of his testicles in her anus.

Last night I gave Sheila the ol' Idaho Spud Fuck.

Idaho Spudfucker 

The Idaho Spudfucker is when you take instant mashed potatoes and put them inside the girls vagina. You then began to to fuck without a condom and use the cum and "love juices" to turn them into mashed potatoes! Afterwards, you eat the mashed potatoes.!

That Sally girl wanted me to take her to Dinner. So I gave her the old Idaho Spudfucker instead!
