All dictionaries are descriptive by design. Lexicographers document usage, and generally try not to arbitrate it-- the recent 'McJob' controversy illustrates this point well. Dictionaries are a convenient resource for describing broad linguistic trends, and generally take inclusions into their catalogs only when words become distributed beyond their original subcultures. The use of 'concerted effort' to denote focused, strenuous action is pretty well established, especially in American dialect.
Who knows-- if NPR and the NYT keep running articles on 'fixed-gear culture,' the phrases 'fixie' and 'track stand' might even make it in.
