The Tingler Poem by Ima Ryma

Some humans host a parasite
That's found upon the human spine.
When the human is filled with fright,
Tiz then the parasite does dine.
A human scream does cease the feast.
The parasite goes back to sleep.
There is no way to rid the beast.
Only screaming out loud will keep
The parasite from causing death,
Crushing the human spine to make
The human lifeless without breath.
So scream out loud for your life's sake.

When down your spine, tingling appear,
The Tingler does feed on your fear.
