Momageddon 

an apocolyptic , end of the world catastrophic reaction by mom when she discovers you have done something innapropriate/against her wishes.

Characterized by screaming to the top of her lungs, can occasionally become physically punishing. A REALLY pissed off mom.

It was momageddon at my house last night when she found out I skipped school to go to the beach.

-mageddon 

a suffix that is affixed to any word that describes the cause of a situation of relative discomfort derived from the last 3 syllables of 'armageddon.'

As of late, the suffix "-mageddon" has been popularized in the media, trying to make light of an undesirable yet minor situation; however like any pop culture word (or suffix in this case) it's becoming less helpful and more annoying with its overuse.

Related suffix: "-pocalypse"

Can also affixed as "-geddon." hyphen not always used.

The roads are closed due to a recent 'snow-mageddon'

John Madden recently went insane during a football game and it resulted in madden-mageddon
