A mix between someone who is unintelligent ("bimbo") and someone who is quick and responsive ("nimble").

In other words, someone who thinks they are coming up with a clever response, when in fact they sound STUPID.
Person A: Yo, did you see Dom hit that jump? It was amazing!
Person B: Yea your mom was amazing last night too.
Person A: You're such a freakin NIMBO, shut up.

It also refers to someone who is obnoxious or annoying. The kind that you want to drop kick to the forehead.
example:
"Dude, Cammy was such a nimbo last night, I had to walk away from her before I lost it.

News bimbo. Scanky woman hired to increase the sex appeal of a news show instead of actually contribute to the profession of journalism.
One example of a nimbo is Kiran Chetry on CNN's American Morning with her news pimp Ali Velshi; many women on Fox News and Headline News are also nimbos.
