To get one’s dander up means to become angry, to become agitated enough to fight, whether literally or figuratively. Get one’s dander up is an American idiom, there are two possible origins. One theory is that get one’s dander up was a comedic way to express raise one’s hackles, referring to the dander or dandruff that would be stirred by the raising of hackles. The other origin theory concerns the fact that dander once referred to the froth resulting from the brewing of yeast. Getting one’s dander up would therefore draw a picture of billowing froth, a good metaphor for becoming angry.

Get one’s dandruff up is an eggcorn, a misheard rendering of a popular idiom, word or phrase.
