File:Bump into thief 1363.png

In short, a thief pickpockets something off of someone, disguising the act as an accidental bump on the street. The theory goes that a brief, seemingly harmless touch presents all the opportunity a skilled thief needs in order to take what he wants off an unwitting target.

The marking quality of this type of encounter is that the thief usually tries to make as small a deal about bumping into the victim as possible, hurrying away before the mark realizes what happened. This is usually accomplished by a quick "Sorry," and brisk walk away from the protagonist.

Bumping into someone in fiction can indicate a wide range of events, from an early romance, to introducing a clumsy character to showing that the new character is simply prone to shoving people out of the way. What these events all have in common however, is that it is usually made apparent right away why the collision took place. There are times though, when someone will bump into the protagonist, and despite a suspicious amount of attention being given to the moment, the protagonist will play off the event as nothing, and little further attention is given to the collision even though it obviously happened for a reason. In nearly every such case, it is almost guaranteed that the colliding stranger introduced in this scene is a pickpocket at work.

There are a couple signals that indicate this trope:

  • The thief tends to have a disproportionate amount of screentime/attention dedicated to him/her for such a brief moment.
  • The victim tends to brush off the encounter and assumes that it happened for no reason. The same goes for any of his traveling companions.
  • The thief doesn't make a big deal about bumping into the protagonist. The thief doesn't give his name, doesn't try to engage in any extended conversation with the victim, and generally tries to get out away from his mark as quickly as possible. In general, the scene is played off to be as seemingly insignificant an event as possible.

To make it even easier, the thief tends to look shady or untrustworthy in general. If he is child, you can expect him to be a Street Urchin. If the stolen item was something important to the plot, you can be certain that the protagonist and the thief will meet again later sometime after discovering the loss of his missing item, having deciphered what exactly happened.

This can happen in Real Life, but pickpocketing in the real world is usually more complicated than how this trope is typically portrayed in fiction. Professional pickpockets tend to work in groups, and employ a variety of hybridized techniques to distract their victims that involve far more than a simple bump on the street.

While the term "percussion" is usually attributed to the family of musical instruments, as a word it simply refers to the act of one body striking another, hence the trope's name.

A Sub-Trope of Five-Finger Discount. Compare to Affectionate Pickpocket, where contact with the mark is achieved in a more forward manner.
