The "<<" face is an emoticon that typically signifies suspicion or distrust. It is often used to convey a sense of skepticism or a feeling that someone is not being entirely truthful. The two angled brackets "<" represent eyes looking to the side or glancing sideways, while the underscore "" represents a frown or a furrowed brow. The combination of these symbols suggests a person who is looking askance or side-eyeing someone or something. It can also be used to indicate that the person is keeping a secret or hiding something. However, as with any emoticon, the meaning of "<_<" can vary depending on the context and the people involved in the conversation.
