Sure! Let's break down the word "crasher."
A crasher is a noun that refers to a person who attends a party or event without being invited or without paying for entry.
In more advanced contexts, you might use "crasher" to describe someone who takes advantage of a situation or benefits from something without contributing. For example, "The crasher of the meeting shared ideas but did not prepare anything."
While "crasher" primarily refers to someone who sneaks into events, it can also describe: 1. A person who disrupts or crashes a computer system (in technology contexts). 2. Someone who experiences an abrupt failure or collapse (in informal contexts, like "He had a crasher of a career after that scandal").
"Crash a party": This phrase means to attend a party without an invitation.
"Crash on someone's couch": This means to sleep at a friend's place, often without planning.
In summary, a "crasher" is someone who attends an event without being invited. It's often used in social contexts, and it can also imply a lack of contribution to a situation.
