An irrational exhilaration and enjoyment while experiencing the effects of a natural disaster or other destructive scenario.
All these rich white folk driving around the 9th Ward in luxury coaches to go see Brad Pitt pretending to help New Orleans, it's just Yankee disasterbation.
To gorge on the massive amounts of fear-mongering news media that reports on nothing more than tragic and violent events across the country and the world.
The disasterbation in this country was waning after the shooting in Arizona until the earthquake/tsunami hit Japan.
After losing $80 in an all-night marathon of playing super poker for quarters instead of studying for the next day's test, you remark "I should really get to bed and stop this disasterbation."
The act of masturbating so hard and so intensely that your penis falls off into a dark hole/vortex only to be later eaten by angry sexually frustrated unicorns.
"Last night I disasterbated, and it seems I will never be sexually pleased again. Cursed disasterbation !"
