I'm not really sure if this is worth a post of its own, but if I make it number one in a series of occasional new word lists and tag each post in the series with the new words label, by the end of the year we might have lots of new words...and it might be useful to someone.
Anyway, for today:
Clicktivism - blend of click and activism, related to online petition signing (from The Guardian).
Slacktivism - blend of slack/er and activism, related to lazy activism or not doing much but just clicking to sign a petition but but actually getting involved (from The Guardian).
Carmageddon - blend of car and Armageddon, relating to apocalyptic prediction that LA roads would grind to a halt as a bridge was demolished. Didn't come to pass, a bit like the rapture, I suppose.
Eurogeddon - blend of Euro and Armageddon, relating to apocalyptic judgement day for European currency (today, apparently)
Dollargeddon - blend of Dollar and Armageddon, relating to apocalyptic judgement day for USA's currency if braindead republicans don't back down (very soon, apparently)
