How does Poseidon assert his displeasure?

Poseidon hated his father, Cronos, for pretty good reasons if you know the story. Cronos had heard a prophecy that his sons would overthrow him and obviously he didn't want that, so he swallowed his children Hestia, Hades, Poseidon, and Demeterin that order. His wife, Rhea begged him to stop when Hera was born. But Cronos was relentless and swallowed Hera anyway. Rhea was distraught when Zeus was born and went to the oh-so-wise Metis for a solution. Metis wrapped a big rock in a blanket and told Rhea to give it to Cronos. He swallowed it down, squishing poor Hera. Zeus was instructed by Hera to run very far away. Then Cronos got very sick and puked them all up. Gross, right? Anyway Poseidon, Hades, and Zeus got back by --you guessed it--overthrowing him! And then they locked him for eternity in a cave. Obviously, some hard feelings there. And that is why Poseidon hates his father.
