wear her heart on her wall

1. to publicly expose one's emotions on one's facebook wall; a twist on the old phrase "wear your heart on your sleeve."
2. to communicate feelings and thoughts specific to one person by posting on one's facebook wall, knowing the specific person will see the post on his/her newsfeed

Suzie's facebook wall post: "Don't cry because it's over, smile because it happened."

Mark: So, you and Suzie broke up, huh?
Johnny: How do you know that?
Mark: Well, she does tend to wear her heart on her wall.
