最近常有人问我Middle Name是什么意思，本人表达能力有限，支支吾吾解释不清，今天特地上Wikipedia找比较正宗的定义：
　　Many people's names include one or more middle names, placed between the first given name and the surname. In the West, a middle name is effectively a second given name. In the United States there is usually only one middle name, abbreviated by its possessor to the middle initial.

　　关键是这段：
　　Since 1905, "middle name" gained a figurative connotation meaning a notable or outstanding attribute of a person. This figurative use is especially popular in films.
　　Sloth is my middle name就是figurative use。
　　《老友记》里Chandler有一段台词也是这个用法：“I can handle this. "Handle" is my middle name. Actually, "handle" is the middle of my first name.”
　　感觉用到XXX is my middle name这个句式，通常都是比较搞笑的时候。

　　Wiki上还有一段竟然提到了中文里的Middle Name，有点晕啊：
　　Most Chinese Americans anglicize their Chinese given name and convert it to an authentic middle name, after a native English first name, such as Bruce Junfan Lee, James Chu-yu Soong, and Jerry Chih-Yuan Yang. The Chinese given name usually has two characters and it is usually combined into "one" middle name for better organizational purposes, especially with Cantonese names, such as Bruce Junfan Lee or Bruce J. Lee. There are also a minority whose Chinese given names are their first names, and have English middle names.
　　这么说我要是去了美国，名字就是Dorothy Xiao-yang Chen了……

　　今天还更新了背景音乐：Hooverphonic组合的代表作Mad About You。大家仔细听的话，也能听到Xxx is my middle name哦！（不是Mad is my middle name……）
