A sexual act preformed in group sex. This occurs when the male directs multiple women to lay on top of each other so he can proceed to have 'doggie-style' sex with them with minimal transitional effort. The reasoning for including 'Salt Lake City' in the name of the act is mainly because, Salt Lake City, UT has a Mormon population of roughly 60%, thus explaining the polygamy joke.
Alex: Did you ever end out seeing Semen Sippers 5?

Max: Yeah, that guy got Jenna Haze and Lela Star to do the ol' Salt Lake City Stack about twenty minutes in, it was flossy.

Salt Lake City is the capitol and largest city in Utah. While famous as the headquarters of the LDS church, Salt Lake is only about 40% mormon.

Salt Lake is one of the few liberal/democratic areas in the predominantly republican state.

Salt Lake is close to the mountains, so the area has great recreation. Many residents ski, snowboard, hike, etc.

I really enjoyed living in Salt Lake. Its a beautiful city with great people. There is always something going on, like free concerts, or drum circles, or festivals. Plus, they have a really nice transportation system, so its easy to get around, even if you dont have a car.
I cant wait to move back to Salt Lake City, UT!

A sexual act, preferably unique to Utah (see "soaking") that occurs in a brief moment while passing through Salt Lake City.
Captain Beerhound, a airline pilot, had a brief, unsatisfying hook-up with a flight attendant in the Delta Sky Club during a Salt Lake City Layover. He later learned that what he had experienced was"soaking," a custom quite popular among some religious folk in Ski City, USA.

Greatest fuckin city in the USA. Too many god damn mormans. There is nothing to do, gets too cold then too hot in about one week. Yuppies are everywhere. Good hot rod scence. Punk scence rules the west. When bands from out of state come here they usually get beat up. I.E. Dropkick Murphys a few years ago and Casualities a few weeks ago.
Fuck LA, Boston, and New York; This is salt Lake.
