What is a snowman's favorite Mexican food?

The joke “What is a snowman’s favorite Mexican food? Frozen brrr-itos” plays on the word “burrito,” a popular Mexican dish, and the cold nature of snowmen. The humor arises from the pun “brrr-itos,” where “brrr” is an onomatopoeic word used to express the feeling of cold, and it’s combined with “itos” from “burritos.” The joke cleverly suggests that since snowmen are made of snow and are inherently cold, they would prefer their burritos to be “frozen” and cold as well, hence the term “frozen brrr-itos.”
