FDA 

Facebook displays of affection. When we've thought we've had enough of too much PDA at times.. now we must deal with the spamming of over-the-top unnecessary wall posts, photo comments, and status updates from couples on our dashboards on Facebook. Instead of saying, "GET A ROOM!" we must now resort to, "GO ON CHAT!!"

Boy: @Sally you are my one true love, I love your lips
Girl: @Johnny oh bby we'll be together 4ever<3<3
Annoyed innocent Facebook lurker: @Sally & @Johnny stop the FDA and get on chat to save us all from barfing, please.

FDA 

The abbreviated version of "Facebook Display of Affection." Posting overly-affectionate content on Facebook on a person's wall or in a status that anyone can see.
Taken from the phrase "Public Display of Affection," or "PDA."

Tom and Jane keep posting all of this lovey nonsense on each other's walls. I'm sick of seeing their FDA everyday!
