emoticon (n.)

“表情符号”是指使用标点符号或其他键盘字符来描绘面部表情的图像表示，该词于1992年出现，似乎源自 emotion + icon。

An emoticon is an emotional icon, or a pictorial representation of the emotions of the moment. These are most commonly created on one line using the symbols on the keyboard. Humor is often denoted with the smiley face :-) which is more obvious if you tilt your head to the left. ["Acronyms, Emoticons, and Lurkers," PC Magazine, August 1992]

表情符号是 emo 情感表达的 icon，或者是当下情感的图像化表现。这些通常使用键盘上的符号在一行上创建。幽默常用笑脸 :-) 来表示，如果你把头向左倾斜，就更明显了。["Acronyms, Emoticons, and Lurkers," PC Magazine, August 1992]
