爱思英语编者按：注重形象的人出门前需要花很多时间打理自己的发型，不过有些人的发型，怎么打理也总是像鸟窝一样，比如伦敦市长Boris Johnson。不论怎么打理，总有那么一小撮不听话的头发立在那里。这一撮头发有个可爱的名字——奶牛舔。

 
Do you ever fight with your hair? You wash it and comb it and try to get it to look perfect. Just when you think you've succeeded — boing! — an unruly clump of hair stands up as if to shout “Look at me!”
你是否曾经和头发斗争过？你洗了头，梳理整齐想要保持一个完美发型。当你以为你已经把所有头发都整理好的时候，嘭！有一小撮不听话的头发竖了起来，仿佛在喊着：“快看我啊！”
 
Don't worry. You're not alone. Almost everyone has at least one cowlick.
别担心。又不是只有你这样。差不多每个人都至少有过一次“奶牛舔”的经历。
 
Sometimes they're barely noticeable, but sometimes they're a defining feature.
有时候，这一小撮头发不是很显眼，但有时候他们会成为你的标志性特点。
 
A cowlick — sometimes called a "hair whorl" — is a small group of hair that either stands straight up or lies in the opposite direction of the way a person wants to comb his or her hair.
奶牛舔，有时也叫头发旋，指一小撮立起来或者朝平时所梳的发型反方向突出的头发。
 
If you've ever spent much time on a cattle farm, you may have noticed that cows have a habit of licking their young. When they do this, their tongues leave a swirling spiral pattern in their hair. The same spiral pattern in human hair has been called a "cowlick" since at least the late 16th century.
如果你在养牛场待过，你应该注意到奶牛都喜欢舔她们的幼崽。舔的时候，她们的舌头会在幼崽的毛发上留下一个漩涡样的形状。那个形状跟人类头发上被称为“奶牛舔”的形状一样，而且，这个说法从16世纪就有了。
