Yesterday,
There's no double entendre for "gay."
Just meant "acting in a happy way."
No thoughts of queens in yestergay.

Suddenly,
It meant men who sometimes act like she
Or dyke gals—whoa! Mal mot, not PC.
But yesterday, gay meant "carefree."

Then things changed, we know
Why's that so? I cannot say.
The word isn't long,
But now gone is yestergay-ay-ay-ay.

Yesterday,
Love of same sex was not labeled "gay,"
But such thoughts one had to hide away.
So book I cleave, check lex of "gay."

'twasn't always so; it meant 'ho'
For gals astray.
For those who swing schlong,
It meant long-ing for a lay, lady lay. . .

. . .Seventeenth
Century. Then semantic shift, "gay":
Early twentieth until today,
We mostly mean it, sex this way:

Boy and boy or gal and gal.
