Facebook Display of Affection, a variation of PDA. Some douche uploads a profile pic of him/her making love with their wonderwall. Usually to the disgust of their peers.
Some bitch is violating FDA regulations, check it! They're doing the nasty on her prof shot.

Similar to a PDA (public display of affection) and FDA is a "Facebook Display of Affection". These are annoying and are most commonly seen by ugly or weird couples

Facebook Display of Affection. Posting your feelings on your friends, family, or significant other's wall for all of their friends to see.
It was my birthday today, my wall was covered with 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!
