Today is a very special visual day in the world of Twitter.  Given that it's #NationalCleavageDay, it's only expected that Twitter stock up on extremely seductive pictures of many free-spirited women's busty cleavage.  Of course, there are a few troll pictures in the mix from individuals who shouldn't participate in the trend, but the vast majority of posts are pure eye candy.  It reached the top spot of trending topics in the U.S. on Twitter today, March 27th, for good reason.

Check out the many Twitter posts in honor of #NationalCleavageDay, above.
