What is ._.?

The symbol "._." is often used in internet slang and text messaging to convey a neutral or blank expression. It can be used to represent a lack of emotion, confusion, or a feeling of being unimpressed. The symbol is typically formed by using periods or underscores to create an emoticon that looks like a face with a straight mouth and eyes. It is sometimes also referred to as a "stare" or "deadpan" face.
