Carve-Out Your Heart

Ten syllables? I can’t count well enough!
Dividends and rows confuse me so
Square roots, my muse lights me from seventh grade
purple and holding your breath
Like the setting sun through autumn wind
Regret has no place to rear its head
Like Medusa, she will turn you to stone
Yet, Pegasus will rise from bloody neck
and will proceed to
My butcher knife to carve-out your heart
can’t stand staring at your living corpse anymore,
dearie, why don’t you go put something on.
I’d rather you not ruin the surprise
Because that would suck hardcore!
