A little information is a dangerous thing. If a character overhears an acquaintance saying about them, "I'm gonna slaughter that bastard tomorrow..." and walks away before they finish, "...at basketball," well, they've missed a pretty important bit of context that drastically affects the meaning of that statement. And if they assume that this acquaintance literally means to murder them and start taking precautions as if that were the case, they're going to wind up looking very foolish at the absolute least.
This trope is a Narrative Device in which an eavesdropper hears part of a statement or conversation out of context and leaps to the wrong conclusion. It is a very specific aversion of Exact Eavesdropping which was popularized, on television at least, by Three's Company, but is Older Than Dirt. Often Lampshaded or Subverted, but just as often played straight, making it a bit of an Undead Horse Trope.
Often a form of Contrived Coincidence. A common source of Third-Act Misunderstanding. Compare One Dialogue, Two Conversations, a similar trope without the eavesdropping, and Poor Communication Kills, where the speaker and not the listener is at fault for the misunderstanding. See also: Bathroom Stall of Overheard Insults, One Side of the Story, Not What It Looks Like. Can result in half or more of the entries on the Mistaken for Index. The Moving Experience can often happen because of this.

Taiga was so distressed because food is Serious Business for her.

Evangeline: I told you, call me master.
- By the way, the payment was sucking blood from his arm.

Akane then tells Ranma her suspicions about Ukyo's feelings for Ryouga, prompting them to follow and eavesdrop, in time to overhear the following exchange:
