The "o| ∵ o|" emote, also known as the "Small Face Square" emote, is a Japanese emoticon used to convey shyness, embarrassment, or cuteness. It consists of two small eyes represented by "o", a vertical bar "|", and two more small eyes followed by a colon and a backslash to create a blushing effect. The vertical bar represents a closed mouth or a small face, hence the name "Small Face Square".
