A containment breach occurs when a post relating to a specific fandom - often on Tumblr, though not exclusively - escapes its origin and reaches a wider audience than was intended, usually with less context. They often happen with posts that are vague enough to be relatable in different situations, including outside of fandom altogether.

Alternatively, they can also be posts that merely escape the original platform, such as Tumblr, to show up on another site such as Reddit or Facebook, with much of the original fandom context mostly still intact.
