GPS (GPSr): (GPSr is the receiver that GPSes) The Global Positioning System (GPS) is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations. It is the basic source for all geocache.

GPX: GPS eXchange Format or GPX, is a light-weight XML data format for the interchange of GPS data (waypoints, routes, and tracks) between applications and Web services on the Internet.

Geocache: Geocaching is an outdoor sport that involves the use of a Global Positioning System ("GPS") receiver to find a "geocache" (see "cache") placed anywhere in the world and where the Internet is used to provide the datum and coordinates.

Hitchhiker: A hitchhiker is an item that is placed in a cache, and has instructions to travel to other caches. Sometimes they have logbooks attached so you can log their travels. A Travel Bug is an example of a hitchhiker (definition from Geocaching.com).

Letterbox (ing): Letterboxing is similar to Geocaching, but you use a series of clues to find a container. Once you find the container (or letterbox), you take a carved stamp from the box and stamp your personal logbook. You then take your carved stamp and stamp the letterbox's log book (definition from Geocaching.com).

Log Book: A pad with pen or pencil that can be found in most traditional caches. Cachers usually write the date found, a brief description of their experience finding cache, and sometimes either 'stamp' or personalize their log page.
