Bedroom Eyes describes a specific facial expression, half-closed and dreamy, that suggests the person is thinking about seduction5. The look is usually characterized by lowered eyelids, a dropped chin, and a slight upward gaze, sometimes paired with a small smile1. Urban Dictionary contributors describe eyes that look 'big, dreamy, sultry, bold, and seductive,' or that are naturally 'heavy-lidded,' giving their owner a permanently sultry appearance4.

The phrase gets used two ways. It can describe an intentional flirty expression aimed at another person, or it can describe someone whose eyes just naturally read that way in photos and film. Yelp posters compared the look to a 'come hither' glance and debated whether it should be grouped with sleepy or drunk expressions1.

People typically use 'bedroom eyes' as a compliment or a teasing observation about someone's gaze in a photo, film scene, or in person. The common convention pairs the phrase with a suggestive tone, often when talking about celebrities, crushes, or characters in TV shows. The Yelp thread on the topic shows the word being tossed around casually to describe both intentional flirting and naturally droopy eyelids1.
