(n) A Japaneseemoticon used to convey the act of bowing to another. This usually means you admire something of them, or wish to show respect. In some cultures, bowing is also a way of greeting one another (however, if you use this emoticon to greet someone who is not from a culture of bowing, then you will most likely confuse them).
