‘叭咧’ (bā liē) is a dialectal onomatopoeic expression used primarily in southern Chinese dialects (e.g., Min Nan and some Wu varieties) to imitate the sound of sputtering, spluttering, or abrupt, noisy expulsion — often from an animal’s mouth, a malfunctioning engine, or even a person coughing or spitting unexpectedly. Neither character carries its usual meaning here: ‘叭’ typically mimics a sharp pop or bark, while ‘咧’ usually functions as a colloquial sentence-final particle; together, they fuse into a reduplicated, expressive interjection with no literal semantic derivation.

This word is informal, vivid, and highly context-dependent — it appears most frequently in spoken narratives, folk tales, or regional storytelling where auditory realism matters more than grammatical precision. It is rarely written in formal texts but common in oral performance, children’s rhymes, or dialect literature describing chaotic or humorous moments involving animals, machines, or unruly speech.
