gatecrash

To gatecrash means to go to an event or enter a place without being invited or given permission. The word is most often used for social events like parties, weddings, or receptions, but it can also be used for other gatherings such as meetings, concerts, or press events. It usually suggests that the person knows they do not really belong there but goes anyway.

The word often brings to mind someone slipping into a room, blending in with the crowd, or acting as if they belong. Sometimes it is used in a playful way, especially when talking about someone joining a party for fun. In other cases, it sounds more critical and suggests poor manners, disrespect for boundaries, or deliberate intrusion.

You might read about activists gatecrashing a press conference to make a point, or about teenagers gatecrashing a concert because they could not get tickets. In everyday use, though, the word is most strongly linked with arriving uninvited at a social occasion. It is less about physical force and more about entering where you were not asked to be.

So whether it is a mischievous attempt to join the fun or a more deliberate act of intrusion, to gatecrash is to turn up and take part where you were not invited.
