An unwelcome and decidedly unsexy thought that pops into an individual's mind while they are masturbating.
I was trying to rub one out when suddenly I had an o'donnell about a Christine O'Donnell political ad.

An insurgent; someone or something that works against all those around him.

An individual who collapses, like a house of cards, under pressure.

A weak, tampon-like human being or thing who fails to serve his/its purpose and gives away way too much when the slightest pressure is applied. A useless cuntrag.
You know, Mr. President, if I didn't know any better, I'd say that Rush Limbaugh is trying to tear down our republic from within?
Mr. President: Yes, Rush is such a Neil O'Donnell!

You know coach, I'd like to start and play most of the game, but my daddy tells me that I would wilt like a Neil O'Donnell under the pressure.

Bertha: Sally, my protection simply is not working in my high-flow months.
Sally: I do believe the mistake you've been making is purchasing those over-priced, useless Neil O'Donnells.

A big, fat, stinking lesbo douche bag who has absolutely no talent other than smelling up the crapper worse than Ed Asner.

Also, any fat, nasty, smelly broad who thinks it is her job to save the world in spite of the evidence to the contrary and hating all heteros while she pretends to do this.
Oh-oh, Rosie O'donnel is in the news again even though she is a no talent ass clown.
