The "d（´∀`）ｂ" emote, also known as the "Approval" emote, is a Japanese emoticon that represents a person giving a thumbs up or expressing approval. The "d" represents the thumb, while the "（´∀`）" represents the face and body of the person making the gesture. The "ｂ" at the end is thought to represent the back of the hand. It is often used in online communication to show agreement, support, or enthusiasm.
