Gate-crashing, gatecrashing or party crashing is the act of attending an invite-only event without invitation. The person doing the gate-crashing is known as a gate-crasher. Gate crashing is also the act of tracing a signal through logic gates in electronics. Reasons for gate-crashing include avoiding entry fees, gaining access to free food and beverages (often alcoholic) , gaining access to a party that they wanted to be invited to, taking pictures of famous people, having pictures taken with famous people, and more serious crimes like stalking, kidnapping, murder, theft, fraud, and causing general disruptions.
Various techniques that involve blending in with the crowd can be used to gain access to some events. Various measures can be taken to prevent gate-crashers from gaining access such as collecting invitations at the door and employing staff to identify potential uninvited guests, but such measures can still be thwarted by a skilled gate-crasher. The 2009 U.S. state dinner security breaches occurred when Michaele and Tareq Salahi, from Virginia, allegedly gate-crashed the state dinner between President Barack Obama and Indian Prime Minister Manmohan Singh.

In security, piggybacking refers to when a person tags along with another person who is authorized to gain entry into a restricted area, or pass a certain checkpoint. The act may be legal or illegal, authorized or unauthorized, depending on the circumstances. However, the term more often has the connotation of being an illegal or unauthorized act.
To describe the act of an unauthorized person who follows someone to a restricted area without the consent of the authorized person, the term tailgating is also used. ‘Tailgating’ implies without consent (similar to a car tailgating another vehicle on the freeway), while ‘piggybacking’ usually implies consent of the authorized person.

Developmental Topographical Disorientation, also known as DTD, is caused by the inability to segregate landmarks and derive navigational information from them, navigate through a non-verbal process, or generate cognitive maps. This is a newly discovered cognitive disorder in which patients who do not have brain structural abnormalities, such as lesions, and exhibit symptoms since childhood. Not to be confused with healthy individuals who have a poor sense of direction, DTD patients get lost in very familiar surroundings, such as their house or neighborhood, daily. This disorder could stem from a lack of experience in navigation during development and could present in different degrees of severity.
A woman in Vancouver, referred to as Pt1, presented with topographical disorientation in absence of any structural lesions. Despite normal cognitive development, she has never been able to orient with in the environment. Further testing showed that she was able to follow route based, landmark based, and verbal directions to reach a destination in an urban environment. In map based testing, the patient was unable to determine the shortest path between two locations on a map, but was able to follow a route traced on a map. The patient was unable to draw a detailed schematic of her house. Although the number of rooms and their locations were accurate, the spatial scaling was distorted.

The Fifth Beatle is an informal title that various commentators in the press and entertainment industry have applied to persons who were at one point a member of The Beatles, or who had a strong association with the ‘Fab Four.’ The ‘Fifth Beatle’ claims started appearing in the press immediately upon the band’s sensational rise to global fame in 1963 as the most famous quartet in pop culture. At The Beatles’ 1988 induction into the Rock and Roll Hall of Fame, George Harrison at one point stated that there were only two ‘fifth Beatles’: Derek Taylor and Neil Aspinall (the Beatles’ public relations manager and road manager-turned-business-executive, respectively). In a 1997 BBC interview, Paul McCartney stated: ‘If anyone was the fifth Beatle, it was [Beatles’ manager] Brian Epstein.’
The term is not used to indicate the chronology of band members joining the group. Pete Best joined Lennon, McCartney, Stuart Sutcliffe and Harrison on the eve of their Hamburg sojourn, the five using the monikers, ‘The Silver Beetles’ and ‘The Silver Beatles’ (they would experiment with ‘The Beat Brothers’ and ultimately ‘The Beatles’ while in Hamburg with Best).
