Vagrant

A vagrant, sometimes informally referred to as a pikey, was a homeless individual with no permanent address.

They were often ignored by "real people". Some sold copies of the Big Issue and it wasn't unusual for vagrants to die due to weather conditions.

In 21st century Wales, despite many vagrants being classed by the system as missing people, they made easy targets for individuals such as Guy Wildman as they weren't missed or mourned for. This meant that organisations such as Torchwood Three could spend less time providing cover stories for their disappearances. (PROSE: Another Life)
