gearvalanche 

When a pile or mound of over-stacked sporting goods gear in a closet or a shelf collapses all over the floor.

If you add one more Nalgene to that shelf, it'll cause a gearvalanche!

Gladvalanche

The result of one's inability to stack disposable food storage containers properly.

I could tell that my husband had just done the dishes when I found a Gladvalanche in the cupboard.

Gravalanche 

When you're mining in Minecraft, and the gravel on the ceiling of a cave all collapses.

Damn, I was mining, found 11 diamonds, but I lost them when I suffocated in a gravalanche on my way back up.
