脆生生 (cuì shēng shēng) is a vivid, reduplicated adjective that describes food—especially fresh fruits and vegetables—with a crisp, juicy, and refreshingly firm texture. The first character 脆 means 'crunchy' or 'brittle', while the reduplicated 生生 emphasizes freshness, vitality, and uncooked naturalness—not 'raw' in a negative sense, but rather 'alive with freshness'. Together, they evoke sensory immediacy: think of biting into a just-picked cucumber or a sun-warmed apple straight from the tree.

This term is commonly used in informal spoken Mandarin and descriptive writing, especially when praising produce at markets or describing homegrown food. It carries positive, almost tactile connotations—suggesting health, seasonal ripeness, and minimal processing. While it can occasionally describe certain meats or tofu in regional usage, its core domain remains fresh plant-based foods, particularly those prized for their satisfying snap and clean flavor.
