What’s the Vietnamese pun on “Coca-Cola”?

Vietnamese has a kid-level pun on the brand name Coca-Cola: split it as coca + cô la, and the second half reads as cô la in Vietnamese, where cô means “aunt / Ms.” and la means “to yell.” So “Cola” sounds like “the lady yells!” Vietnamese parents and kids' YouTube channels turn this into a small game: “Tôi vừa làm gì? Cô la! Vậy từ nãy đến giờ tôi làm gì? Cô uống Coca-cola” (“What did I just do? The lady yelled! What was I doing all along? Drinking Coca-Cola”).

The pun works because Vietnamese is tonal, and the syllables cô and la land naturally as separate words. Brand names in Vietnamese often pick up jokes like this.
