Foursquare Badge – 4sq Day 2010 (Retired)
Badge Message – “Happy foursquare day! (four squared = 4/16, get it?) Here’s a toast to all of you for making foursquare so amazing and to the 50+ 4sq Day parties going on around the world!”
This badge could be unlocked on 4/16/2010 by shouting “Happy Foursquare Day”. This badge will hopefully be available again next year and thereafter so mark your calendar!
