Moumantai 

無問題 or 无问题

Translates literally as "no problem" but interpreted in English as "relax" or "take it easy" (also written Momentai)

Its a Cantonese phrase made famous by the Bandai show Digimon Tamers, by the Digimon character Terriermon, who it has almost become a trademark phrase.

"Henry, moumantai!" (Literally "Henry relax!")

Big Mountain Skier

Douchebag who thinks he is better than everyone else because he has skied at a large mountain.

Josh thinks he’s such a big mountain skier, all day he’s been saying how small this hill is compared to Colorado.

cumming around the mountain

When a woman gets-off by rubbing herself on your chest.

Man, after the season finale of "Idol" last week, there was a huge after party. I hear that Paula Abdul was Cumming Around the Mountain on one of the contestants! I wish I was there!

Mountain Trash 

Snowboarders, particularly when they are "littered" all over the mountain or ski area. When not scraping snow off the mountain you can find them taking up entire trails either waiting for their turn on a feature at the terrain park or just hanging out on the slopes.

"Dude, that trail had a ton of knuckle-draggers on it."
"Seriously, there was Mountain trash everywhere."

clothes mountain 

A pile of both clean and dirty clothing that forms on top of a bed. The clothes mountain serves joint functions, as both clothes storage and a sleeping surface. It tends to begin innocuously as a stray item of clothing, but quickly builds to a towering height and a base that swallows up the entire bed. It is prone to clothing avalanches, thus spilling dirty underwear and tube tops onto the floor, forming a sort of clothes mountain range. If not treated quickly, the clothes mountain range will become a parasitic addition to the bedroom, hindering passageway in the event of a fire.

"Kay Kay, put your laundry away! Mom doesn't want to see the clothes mountain anymore!"

make a mountain out of a molehill 

To exaggerate, to interpret a specific situation as being worse than it really is.

You don't have to be that worried about this simple situation, don't make a mountain out of a molehill.
