Mountain-ass

noun, the medical condition experienced by female ski resort season-workers wherein rapid and protracted intake of high-calorie, often fried foods (usually justified on the grounds of perceived increase in physical activity) causes expansion of a formerly attractive posterior beyond normal dimensions.

Dude1: Man, this season was too f**kin' ace, but I'm looking forward to rotating back to the world and seeing some girls without mountain-ass.
Dude2: Quite.

mountain tornado

Mountain tornados occur when a funnel cloud develops into a tornado near the base of a large mountain. The rotation of the tornado in such close proximity to the mountain causes a scientifically unexplainable process that forces the tornado up the side of the mountain until it reaches the top. Once at the top, the speed of the tornado accelerates until the tornado begins to sink into the mountain (like a drill bit). The tornado continues down until completely submersed (it sort of just disappears).

Note: mountain tornados are extremely rare. The only confirmed sighting occurred July 29, 2009 at Cheyenne Mountain located in El Paso County Colorado. The storm caused extensive damage to the Cheyenne Mountain Zoo facilities. Luckily there were no casualties (human or otherwise).

Wow! You should have seen how worried my coworker was during that mountain tornado. Her kids were at the zoo while it was happening! Good thing the zoo staff had enough sense to move the kids into a safe / strong structure.

Mountain Time

When someone is late for a meeting and the general assumption is they were a) banging someone, b) batin in the bathroom, or c) any other sexual activity, they are said to be on Mountain Time - irrespective of their actual time zone.

Gary: Who are we waiting on?
Gladys: Lefty, again.
Laurence: Darn him. He's always late.
Steve: Bitch is probably batin' - I'll go check the stalls.
Gladys: Steve - language!
Steve: The dude has KY on his desk! He's on motherfuckin' Mountain Time!
