"Mooo!" (often stylized in all caps as "MOOO!") is a song by American rapper and singer Doja Cat. Originally self-published exclusively as a music video on August 10, 2018, it became a viral internet meme and amassed over 578 million views. It was subsequently released as the lead single from the deluxe edition (and third overall) of her debut studio album Amala. The viral success of "Mooo!" is considered a major factor in Doja Cat's internet fame, ultimately "setting the tone for her career", despite being considered by Doja Cat herself as a "throwaway" and a "joke".
