Traveller

[Vania]

A person who is travelling or who often travels.

[Kai]

[Julene]

British term used to refer collectively to two separate traditionally-nomadic groups found in the UK: Irish [Travellers] (also known as [Pavee], tinkers and pikeys) and [Romani] (also known as Roma, Romany, Romanichals, Romnichals and Kale). The term is used to replace the traditional term gypsy, which is now considered offensive by some. The term refers to members of these two groups regardless of whether they actually live a nomadic or [sedentary] lifestyle.

A term used by people who are travelling away from home, but have distaste for the terms tourist and holidaymaker. Travellers are often said to be distinct from tourists/holidaymakers due to the fact that they travel for longer periods of time, seeing a variety of places in one trip, and make an effort to experience the real spirit of the places they visit, rather than just tourist resorts. Those who self-describe as [travellers] are also often travelling on a tighter budget than traditional tourists, staying in hostels rather than hotels. A roughly synonymous term is [backpacker].

[Tanya Shivari]

An alcoholic beverage, usually a tin of [lager] that is taken for consumption on [public transport] [en route] to the pub/bar/club

[Sonia]

getting a random or [sporadic] erection while travelling, can be quite [embarrasing] and is usually kept [hidden].

[Couch Potatoe]

A [tinker], or member of the Irish travlelling community. See also the British pikey. They live in caravans in random fields and leave the place generally in a mess. However there are some good [travellers] who are given a hard time and a bad name due to the bad ones.
