Mengua is a fascinating verb that specifically means 'to wane' or 'to diminish', often used in the context of the moon's phases. It's not a word you hear every day, making it stand out.
In the song, Becky G sings, "La luna nunca cambia, solo mengua" (The moon never changes, it only wanes). This line uses a beautiful metaphor, suggesting that while things might appear to diminish or fade, their fundamental nature remains the same, adding a layer of poetic depth to the lyrics.
Bold, bilingual and unapologetic, “KILL BILL” is Becky G’s sonic eye-roll at anyone who tries to police her words, her body or her attitude. Over a swagger-filled beat, she turns every critical comment into background noise, slicing through the chatter with lyrics that compare her words to knives. The repeated question “¿Quién te preguntó?” highlights her main message: if she did not ask for your opinion, it is irrelevant. By playfully switching between Spanish and English, Becky shows pride in her Mexican-American identity while reminding listeners that she answers only to herself.
The title “Kill Bill” is more about killing the negativity than literal violence. Think of it as Becky G’s movie-style montage of ditching haters, walking away from anyone who will not accept her as she is, and celebrating self-confidence with a flirty wink. She might invite you to dance or offer a “Kissi boy,” but it is always on her terms. The song is a fierce soundtrack for anyone ready to mute outside opinions and turn up their own volume.
