The "fallout" cocktail

[airbrakes]

This just popped up on Facebook. No info other than that its called a "fallout". I've tried googling it but it seems a common name for lots of other cocktails designed to blow your head off with strong spirits. So, do any bartender types on here have a clue what could be in it, and how its made to get such a spectacular effect? I'd love to have a go doing it myself!
My guess is red curacao and baileys, with vodka or gin inbetween and some chilling of certain ingredients to make them less miscible?

Horrible.

Looks to be sambuca first then baileys on top and just plonk in a bit of grenadine to create the effect. Relatively simple considering the outcome.
