To people raised in a railroad shack
It is known as your butt crack
To people of taste who are verbally deft
It is known as the gluteal cleft
Either way, it's at the bottom of your back
Between the one on the right and the one on the left

Some ladies' swimwear of slender heft
Displays freely the gluteal cleft

On this matter, my mind is shut
Don't walk around showing off your butt
I trust you will not wear one at least
Until I am safely deceased.

Your gluteal cleft, I must insist,
Should be seen by your dermatologist
When treating a rash, or cyst,
And nobody else. No daughter of mine
Wears thongs. That's the bottom line.
That's the bottom line.
No daughter of mine belongs
In thongs.
