Couchsurfing is a form of travel where a traveler, often due to budget restrictions, stays at a private house in a spare room or on a couch while visiting (hence “couch surfing”). The traveler may have met this Good Samaritan through friends or family, or through an online site, such as couchsurfing.com. Couchsurfing is a great way to experience the true culture of the place you are visiting, because you will experience the daily life of a local and taste more authentic food.
Made popular by the alternative travel community, CouchSurfing (www.couchsurfing.com), which allows travelers to meet, host, and “surf” with other travelers. This word is a neologism.
