Yabo (野暮) is a Japanese term used to describe objects or behaviors that are considered unaesthetic, unappealing, or lacking in refinement. It serves as the direct antonym of "iki," which represents an aesthetic of understated elegance and chic sophistication.
Characteristics associated with yabo include qualities such as being coarse, gigantic, loud, superficial, or vulgar. While a non-iki thing is not always classified as yabo, it often is. The term encompasses various traits including childishness, self-consciousness, permanence, and snobbishness.
