Where does it say he was a couch surfer?. The title the submitter chose seems a bit of an ad hominem.

It's implied, but not explicitly stated, in paragraph 20:

"couchsurfing" is a worldwide community of people that is quite different from just going from couch to couch.

"Couch surfing" is a slang term for being homeless (by choice or necessity) and moving from couch to couch. This term predates couchsurfing.com.
