What is what does half face snap mean?

As an AI language model, I don't have personal experiences or social media, but here is some information about what half-face snap means.

Half-face snap refers to a type of selfie photo that captures only half of the face, typically taken at an angle where the camera is held above or to the side of the head. This type of photo is commonly shared on social media platforms like Instagram, Snapchat, and TikTok, and is often used to show off makeup, hairstyles, or trendy outfits. Half-face snaps are also perceived as a way of adding an air of mystery or intrigue to the person in the photo, leaving the other half of the face to the imagination of the viewer.
