The little finger, often called the pinky in American English and pinkie in Scottish English (from the Dutch word pink, meaning little finger), is the most ulnar and usually smallest finger of the human hand, opposite the thumb, next to the ring finger. It is also called the anti-thumb, the fifth finger, the baby finger, or the fourth finger colloquially.
There are four muscles that control the little finger, three of which comprise a group called the hypothenar eminence :

- Extensor digiti minimi muscle
A pinky promise (also known as a pinky swear) is made when a person wraps one of their pinky fingers around the other person's pinky and makes a promise. Traditionally, it's considered binding, and the idea was originally that the person who breaks the promise must cut off his pinky finger. In a similar vein, among members of the Japanese yakuza (gangsters), the penalty for various offenses is removal of parts of the little finger (known as yubitsume).
Also in Japan, holding up a pinky while speaking of two people signifies that they are in a relationship. This pinky substitution is considered vulgar and old-fashioned, however, in some anime scenes is intentionally used to enhance its silliness.
In China, if one holds up a little finger at another, it is usually considered vulgar, just as holding up a middle finger in the United States and other countries is generally regarded as offensive. In addition, in the United States, wearing a ring on the pinky finger has some symbolic meaning. The pinky finger is the relationship finger. If you wear a ring on the pinky finger, you are open and loving.
In India, holding up the little finger is also a signal of "katti" or a broken friendship, a sign that someone is angry, or a playful suggestion that the person flashing the pinky is not going to speak to you.
In India, holding up the pinky is a signal that the person has to urinate.
Similarly, in Indonesia, when a man points his pinky finger downward it is a signal that he needs to urinate.
In Turkey, it's tradition to link pinky fingers when two people are making a bet.
In the United States the Engineer's Ring is a stainless steel ring worn on the fifth finger of the working hand by engineers that belong to the Order of the Engineer and have accepted the Obligation of an Engineer.

In some Western cultures, the wriggling or bending of the little finger indicates a small penis, an insult to the person whom it is directed at. The Australian Government used this in a recent advertising campaign against speeding, depicting females bending their little fingers at speeding males.
