make somebody’s hackles rise – to greatly irritate, annoy or aggravate someone

The example sentence refers to ‘outlandish behaviour’. ‘Outlandish’ is an adjective which means strange and unusual and difficult to accept or like.



If you haven’t heard this idiom before, I am not surprised as it is not a common expression. Being able to use it accurately, though, can make a good impression.
