^^ Yeah, good point. That's probably why she's still around.

^ Hmm… hey, you remember, after Harry Stunned Umbridge and Yaxley in the courtroom and rescued Miss Cattermole, they just left Umbridge and Yaxley lying unconscious on the floor in the same room with a bunch of dementors: so why do you think they didn't Kiss them? (Please answer this seriously, this is a canon Q&A)

Umbridge smells like limes.

WHAT

I thought maybe she smelled like poisoned honey? /ref

Please answer the canon question.

I don't know if they were kissed or not

No they weren't. Proof: Yaxley came pursuing the protagonists about 3 minutes after they has left the courtroom, and Rowling stated that Umbridge was sent to Azkaban after the war for crimes against Muggleborns — neither of which would have been possible if they had been Kissed.

Yup, you're right

I can't believe "kiss a Dementor" has won out over "kiss Umbridge" again!! Why does this keep happening??!!

Also, Dementors can't be killed, Opal.
