The term "wrinkly brain" refers to someone being very intelligent or thinking in a complex, highly analytical way. The structure is a humorous metaphor based on the idea that brain "wrinkles" (cerebral folds) are associated with higher cognitive capacity. It is informal internet slang, often used playfully or sarcastically to praise clever thinking or overly complicated reasoning.
