‘嗦溜’ (suō liū) is a vivid, onomatopoeic verb describing the action of sucking something—especially a small, slippery object like a bone or gristle—while simultaneously sliding or pulling it out of the mouth with a quick, wet motion. The first character 嗦 evokes the sound and sensation of vigorous sucking, while 溜 conveys smooth, rapid movement, often with a sense of slipping away. Together, they capture a very specific physical action common in informal, descriptive speech.

This word is used almost exclusively in colloquial contexts, especially when talking about eating meaty bones (like pork ribs or chicken wings) or handling small animal parts. It’s frequently heard in storytelling, food commentary, or casual conversation among family or friends—never in formal writing or polite registers. Native speakers often use it with expressive tone and body language to emphasize the tactile experience: the resistance, the slipperiness, and the final ‘pop’ as the item releases.
