shove piggy-in-the-middle shove 

impractical and thus rather unpopular version of the renowned parlour game shove piggy shove.
requires three players: two to play shove piggy shove as normal, and one to stand in the middle flailing their arms and shrieking in an attempt to intercept the ball.
the reason this game is unpopular is because it relies more heavily upon luck than skill, and we all know that shove piggy shove should be a game of skill.

"anyone fancy a couple of rounds of shove piggy-in-the-middle shove?"

Steamy Piggy 

Cook some bacon around a dowel or sausage. Then take it off and secure it around your dick. Take your lady (has to be one of them real debutante ladies) into a sauna and show her your ham. Then pork her up the butt.

Billy: Hey! Bruno! How was your date with Meghan?
Bruno: Great! I took her to a spa and gave her a steamy piggy in the sauna.
