going mashed potatoes 

Going "Mashed Potatoes" on someone is where you perform the act of pulling down your partner's pants, smearing mashed potatoes (any flavor will do) onto their buttocks, and "motorboating" them between the cheeks. If done correctly there will be mashed potatoes strewn about the area where the act had taken place.

Tom: "Check out that girl in the yoga pants", Earl: "Oh yeah, if I had the chance I'd be going mashed potatoes on her all day"

mashed potato ass 

An older woman's ass that is rotund and full of cellulite dimples. When they sit down, the ass seems to squish and go all over the place, as if they were sitting on a pile of mashed potatoes.

My sixty-five year old teacher has a mashed potato ass. It is very distracting.

These mashed potatoes are so creamy. 

From the movie "While You Were Sleeping". The family sits around the holiday dinner table making inane conversation. This line is used as a response when people are talking about useless information. A similar line from the same scene is, "John Wayne was tall." The line is even more powerful if someone else responds with this line.

Person a: "Justin Beiber was at the mall today."
Person b: "I love him, he is so gorgeous!"
Person c: "These mashed potatoes are so creamy."
Person d: "John Wayne was tall."

FF: dafuq is that shit?

Officer to rookie: Stay away from him, he's got mashed potato brains.
