To cause discomfort, inconvenience, or trouble to someone; to disturb or upset.
From dis- + accommodate (from Latin accommodare, 'to make fit or adjust'). Rather than accommodating or adjusting for someone's comfort, this means doing the opposite—creating discomfort.
It's interesting that 'accommodate' became such a common word while its opposite, 'discommodate,' virtually disappeared from English—we just use 'inconvenience' instead, but 'discommodate' has this wonderfully old-fashioned sting to it.
