How did Odysseus anger Poseidon?

Odysseus angered Poseiden by blinding the Cyclops, who was Poseiden's son. Odysseus jeered at the Cyclops and taunted him for eating his visitors in his own house, and then proceeded to blind him.

Here’s the key passage from Book IX:

Then, when I had got as far out as my voice would reach, I began to jeer at the Cyclops.

“‘Cyclops,’ said I, ‘you should have taken better measure of your man before eating up his comrades in your cave. You wretch, eat up your visitors in your own house? You might have known that your sin would find you out, and now Jove and the other gods have punished you.
