Snowmageddon's weaker/wetter cousin. When you get a shit ton of snow followed immediately by a warm front that turns it all into slush creating massive amounts of standing water and ice slushy. This is then in turn tossed around by idiots in cars indiscriminately like a rain/hale storm in a twister causing weeping and gnashing of teeth on your way to work as your car is slowly eroded away from the raw mixture of water, deicing chemicals, ice, salt and gravel.
Oh my god I almost drown on my way to work today. It was a regular Slushmageddon out there.
Or
Holy shit my car was pulverized this morning by all the yahoos driving in Slushmageddon
At my current rate of slackage, I'll eventually drop out of college in about two years and become a homeless bum after being disowned by my parents. I'll live in a cardboard box in the Yukon territory, then get mauled to death in the wilderness, as punishment for my slacking off.
