Stink-eye is an informal term that describes a look of disapproval or contempt that someone gives another person. It is typically conveyed through eye contact and can be perceived as very unpleasant or uneasy. Some other synonyms for the word stink-eye could include dirty look, side-eye, glare, scowl, or even dagger-eyes. These words all capture a similar sentiment of negative judgment or dissatisfaction communicated through someone's gaze. It's worth noting, however, that there's no one-size-fits-all word that could do justice to the complexities of non-verbal communication. The meaning behind a look or a glance can vary greatly depending on the situation, cultural context, and the individuals involved.
