"but if we’re verbing"?

It is a joke.

The word "verb" is not a real verb (it is a noun). However the joke verb "to verb" means to change a noun into a verb.

Monica Lewinsky is famous for having oral sex with then President Bill Clinton. She wore a blue dress which had an infamous semen stain on it that was part of Clinton's legal trouble resulting from the affair.

Beyonce used the noun "Monica Lewinsky" as a verb to mean "spill semen on a dress during oral sex" in one of her raps. The original Beyonce line was "He popped all my buttons, and he ripped my blouse. He Monica Lewinsky-ed all on my gown."

Monica Lewinsky was pointing out that it was wrong to use her name as a verb to mean "spilling semen". It was in fact Bill Clinton who spilled the semen.

The better lyric would be "He Bill Clinton-ed all on my gown".

Ms. Lewinsky has a point.

Excellent explanation.
I wonder what the word Partition means there.

The lyrics say



She is in a limousine. The partition in this case separates the limousine driver in the front from the passengers in the back.

She is about to give oral sex to her male companion. The partition, when it is up, will prevent the driver from seeing her do this.

I feel I should say, these lyrics are not very profound or even very good.

Americans don't generally talk this way.

Does yoncé refer to herself: Beyonce?

Yes, it means Beyonce.

What's that?

I disagree, Clinton is known for lots of things, Lewinsky only one.
