Equal parts Citrónge, Stolichnaya, and Cuervo Gold tequila. Add a dash of Coke (black, like your heart), a twist of lemon (simultaneously bitter and sweet, like the feeling when you take life), and then float grenadine on top (red, like the blood of your victims).
The hamfisted bartender at Red Lobster does not understand how to float things, but it tastes the same at the end. He also thinks that everything is served in a pint glass as a default. Two pints of these babies will do you just fine.
