The term 'creepy gaze' can be summarized by the four-letter word 'LEER'. A LEER is a type of facial expression that is often used to convey a feeling of being sinister or creepy. It is usually characterized by a sly, knowing look in the eyes and a slight smirk on the lips. The person making the LEER may also raise one eyebrow or tilt their head in a certain way. This expression is often used to make someone feel uncomfortable or intimidated.
