Snowmageddon 

When a little predicted snow wrecks havoc with your day to day life and amounts to nothing but a little dusting.

The weatherman predicted a 1 inch snowfall, it was snowmageddon at the grocery store.

Snowmageddon 

A term Environment Canada coined in December, 2008. About 15 cm fell in the City of Toronto on December 19th of that year. The term gave credence to the rest of Canada's perception of Toronto as the "laughing stock of Canada"

I see they're calling the storm in D.C. Snowmageddon, but we all know those guys at EC called Toronto's storm that first.

Snowmageddon Syndrome 

The diagnosis of boredom and insanity due to the large amount of snow. This occurs when there happens to be so much snow that you are not able to go anywhere nor see anyone.

Person 1: Hey have you talked to Tom lately?
Person 2: No, I've heard he has snowmageddon syndrome, he sits on his couch watching cat videos on his computer all day.
Person 1: How sad.

Snowmaggedon 

When a huge winter blizzard surpasses a previous large winter storm (see snowpocalypse) and dumps copious amounts of snow in a place unprepared for such large snowfall amounts thus grinding entire transportation, retail, school and government systems to nearly a complete halt for several days. Results in extreme cabin fever leading to massive snowball fights and excessive photography.

I've been trapped in my neighborhood for five days now without mail, phone or electricity because of the Snowmaggedon !!!
