I think petulant man-child is a more apt description.

Arizona Gov. Jan Brewer said that her tarmac confrontation with President Obama on Wednesday showed him to be a little oversensitive.

“He brought up my book. And he was a little tense. I asked him if he read my book, ‘Scorpions for Breakfast’ and he said he read the excerpt and he didn’t think that I was very cordial,” Brewer told radio host Mike Broomhead on KFYI radio. “He was somewhat thin-skinned and a little tense to say the least. I was trying to be very calm.”

“The book is factual, the book is true,” Brewer repeated on Fox’s Greta Van Susteren show. “I don’t know why he was surprised by my book but he evidently is and he’s very thin-skinned in regards to it.”
