An abbreviation of dancefloor, origininates from teen lingo in Australia. Very popular among elder teenagers and young adults especially those that frequent pubs and clubs. A much more contemporary version of the 'd-floor' - which is a word that should never be said out loud unless you wanted to permenantly socially isolate yourself. 'The DF' is socially acceptable and is not considered to be lame.
