Serial killer

It's a beautiful cadaver A wonderful backstabbing Horrendous knife holes Not happily ever after It's shattered The dream so sought-after It only made me madder See her pitter-patter Blood flowing down Like puddles of red lobster I got what I was after Now what's the matter Do I need to purposely lather Up like soap To wash away your hope Or fill you full of holes And just elope Without the rope Hanging from a cross instead Either way we're all dead Dead inside No tears to cry Why? I was raised like that I guess You don't have to undress To get me to confess To the stress That's got me feeling this test I know I'm a mess at best That's why we're all in duress Staring at her blood-soaked dress That's what they get for making me out to be nothing but a pest
