I have finally found the cocktail I was looking for. It’s called, “An Alien Brain Hemorrhage”.
According to TYWKIWDBI, to make an Alien Brain Hemorrhage:
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.
The only other way I know to make an alien brain hemorrhage is if you get abducted by aliens and they cause you to burst an artery in the brain. This would be followed by localized bleeding in the surrounding tissue that kills brain cells.
The great thing about both kinds of alien brain hemorrhages is they both kill brain cells.
