I Know No Better Word

Once, by many, score 'pon score,
I know no better word for whore.
Would that I could slit a throat;
And take such meassures to garrote.
The pains I'd take to decimate
Each pound from mine, aleviate.
Imagine, thus, each length undone,
Taking pleasure; taking fun!
Merciless I will be with pride;
Knowing such by which you died.
Bathed in wine from what before,
I know no better word for whore.
