n. excessive Facebook activity related to one's significant other that is uneccesary and disgusting when it pops up on one's friends' newsfeed. Common examples include, but are not limited to, the following:

1. Use of the word "baby" after every word written to one's significant other.

2. Making every status update about one's bf or gf.

3. Having full blown conversations under comments on a wall post, when you damn well know, you could have just picked up the phone and talked to them if you loved them so much.

4. Posting picutres of the two of you, even though they are blurry/you both look awful, just to prove you actually are in a realtionship that exists beyond your fb wall.

The nauseatingly touchy feely Public Dispays of Affection posted on the walls of Facebook pages.

Keep it to text messages, phone calls or better yet a hand written note. The rest of us don't want to gag on your lovey dovey chatter.
"FB-PDA = I am so happy to have you in my life, you are the sweetest boyfriend in the whole world. I can't imagine my life without you. I love you baby. Thank you for the amazing weekend at the beach."
