What is the meaning of sulk in one's tent?

Answer 1

"Sulking in one's tent" means to withdraw from the action or quit the game because you think you've been insulted or treated unfairly. The reference comes from The Iliad. The Greeks' greatest hero, Achilles, refuses to join in the fight against the Trojans because he feels his honor has been slighted by Agamemnon, commander of the Greek army. When Agamemnon was forced to give up one of his war prizes-a captive girl named Chryseis-he helped himself to one of Achilles' war prizes, the girl Briseis. While the war rages on and the Greeks are faring badly, Achilles sulks in his tent. No amount of begging and pleading persuades him to re-join the battle, until his best friend Patroclus (wearing Achilles' own armor) is killed.
