old fashioned To put someone in an irritable, grouchy, or unhappy mood; to make someone feel unwell, displeased, or in poor spirits. Primarily heard in UK. Having lived in Gibraltar for most of my life, where the weather remains temperate throughout the year, I must say that these awful London winters put me quite out of humour. It always puts me out of humour to think about the state of our country's political system for too long.
