The phrase, "Invitation Only" doesn't apply to the contestants on this reality show that has players trying to sneak into weddings, reunions, conventions and other parties. If the participants manage to make it past the velvet rope and sneak into an event, they will have to test their guile and guts as party crashers as they perform a series of tasks at parties to determine who is the ultimate party crasher. Crash Test will put the life into any party -- it's not a party until it's been crashed!
