Netflix and Krill.
Explanation: This joke plays on the popular phrase “Netflix and chill,” which typically refers to a casual romantic encounter involving watching Netflix together. In this case, “krill” (small marine creatures that are a primary food source for blue whales) replaces “chill.” The humor arises from the unexpected twist of the whale’s diet being incorporated into the familiar dating reference, creating a playful and punny connection between marine life and modern dating culture.
