Couch tour is when a person with no home manages to have a roof over thier head every night they sleep. People who do the couch tour usually will stay with a different persons place every few days to a couple of weeks, and will mooch or freeload and annoy the host; until the host tells the person to "get the fuck out". People that typically do the couch tour have multiple substance abuse issues, lack interpersonal skills and can not hold down a job.
My friends brother is an alcaholic meth tweaker, who can't hold down a job. He has no pernament address and stays with whoever will put up with him. He is constantly staying at different places, basically he is doing the couch tour.
A gawker or rubbernecker that stairs at disasters, accidents or people in the process of misfortune. For example there is a car accident on a street and a looky loose (or looky lou) will ride by, slow down and turn thier head to check out the scene. A looky loose will also be one of those people that are always there to see fire fighters or EMTs in action when they are in thier neighborhood.
