My 21st Century Thong

I saw the most 21st century thing,
A girl with a tattooed on thong.
Not silken, or cotton, or held up with string,
The concept of 'undies' undone.
It might save the laundry and ironing as such,
But increasing the number of holes in your crotch,
Is unnatural and doesn't appeal to me much.
It seems fundamentally wrong.
