mega drop 

Same as a Mic Drop but done to authorities figures.
It refers to a megaphone.
And it's mostly metaphorical.

Punk'd Churchill was a huge mega drop!

Megadropdead 

When more then 1000 people die simultaneously (in a time span of max 70 minutes and in a 100km radius) with no clue what possibly could be the cause

There hasn't been a Megadropdead yet, its plausible but ridiculous unlikely.
