Doorsluipen

Doorsluipen is a Dutch term used to describe the act of moving through a doorway during the moment it is opening or closing. It can refer to a literal movement—passing through a doorway quickly without stopping—and to a figurative act, such as exploiting a brief opening in a barrier, procedure, or policy.

Etymology and usage. The word is a compound of door (doorway) and sluipen (to creep or slip). In everyday Dutch, the term can describe ordinary or incidental moments of slipping through a door, but in professional and media contexts it is often used to discuss security risks or narrative devices that hinge on a doorway moment.

Contexts and interpretations. In security discussions, doorsluipen is connected to tailgating or piggybacking, where an individual follows another through a door without proper authorization. In everyday life, it might simply describe catching a door before it closes. In storytelling and film analysis, the term can be used metaphorically to describe a character entering a scene at a critical moment through an opening, or the way a scene relies on the proximity of an opening to progress.

Related concepts. Closely related ideas include tailgating, piggybacking, and the broader notion of exploiting timing windows or bottlenecks in systems or environments. See also terms such as door closer, security loophole, and timing-based strategies.

Notes. Doorsluipen remains a descriptive term and is not a formal security standard, with its meaning largely derived from context and usage in Dutch-language discourse.
