Emoticon
Single or multiple ; (Semicolons) are often used together with faces depicting embarrassment, for an added effect. Also, other characters may be added to indicate hands, similar to the Japanese emoticons; but usually they are only attached on the right. Example: -ㅅ-a (scratching one's head), 'ㅅ'b (Thumbs up), 'ㅅ'ㅗ (The finger)
