verbal osmosis
The act of checking your mail, facebook and twitter accounts, checking out the new additions to lolcats, failblog, roflrazzi and urban dictionary, checking nhl and ufc highlights, etc, all while your teacher is lecturing you, hoping that some of the talk that is washing over you will stick in your head.
"Life's too short to listen to this crap. Hopefully i'll accidentally learn enough to pass via verbal osmosis."
