This short clip is Vegeta saying 'Iinaa,' the Japanese word for wishing something were yours, in a drawn-out, envious tone that lasts under a second. It lands as playful jealousy, the sound of admiring someone else's luck while pretending not to care. The line comes from Dragon Ball, where his proud rivalry makes the envy feel both funny and in character.
