It's actually pretty easy to make. I am trying this ASAP.
According to LatinRapper.com:
To make an alien brain hemorrhage cocktail, fill a shot glass halfway with peach schnapps. Gently pour Bailey's Irish Cream on top. After the shot is almost full, carefully add a small amount of blue curacao. After it settles, add a few drops of grenadine syrup.
