What does "side eye" mean?

“Side eye” on social media means a look or reaction of skepticism, disapproval or subtle judgment towards something or someone. It’s used to convey sarcasm or a silent “Are you serious?” moment, when you’re feeling doubt or amusement but not calling out the subject. The side eye emoji or gif is used to add humor or shade in online interactions.

The concept of “side eye” comes from a nonverbal gesture—someone glancing sideways without turning their head, often implying suspicion or lowkey dislike. It’s like that sly look someone gives when they’re not buying what someone else is saying or when they think something’s a bit off. 

On Twitter, TikTok, and Instagram the side eye expression (whether in emoji form 👀 or a side-eye gif) means “I’m judging” or “I don’t quite believe you.” People use it to react to everything from someone exaggerating a story to a questionable opinion to awkward situations.
