Greasy slide 

When both male and female ejaculate on to the floor after coitus, then use it as a slip n slide.

Hannah very much enjoyed her greasy slide with Nathan.

keep the greasy side down

An action; as in travel safe or keep your vehicle on its tires. Keep the underside of your vehicle to the ground...keep the greasy side down! The undercarriage of older vehicles especially, could be found unusually greasy and full of oil. In instances where there may be an oil leak on your vehicle or the exhaust was excreting oil.

You're heading out on your road trip to Yellowstone Park? Well then, keep the greasy side down!

greasy slider 

That untimely irritating dump you have to take immediately following getting out of the shower.

I would rather take a dump before I get a shower because I hate dropping a "greasy slider" after a shower.

Greaseslide 

A greaseslide is what will happen when bacon is elected with an overwhelming vote in 2012 and becomes baconator! A baconator is a benevolent and wise dictator who rules in a Baconocracy! Baconocracy is the choice to unite not divide... Bacon will rule wisely and benevolently. In this politically divided country our best hope for unity is to unite behind bacon in the bacon party. Only bacon can win a true mandate. The bacon party has a vision of world peace where all the diverse peoples of the world unite behind bacon. As we all know, bacon makes everything better. The motto of the bacon party is VOTE FOR GREASE!!! Bacon is the last best hope for the USA!!! Elect bacon in a greaseslide!

In 2012 the bacon party candidate, bacon, was elected in a greaseslide when the people chose a baconocracy!
