On this facebook quiz, it just said:

Pick someone to do PDA in front of:

1.My friends, so they can see how lucky I am.
2.My ex, so they can see that I've moved on.
3.Anyone who's around.
4.Ew! No one!


... So does anyone know what PDA means, I looked on Google and it said a computer thing?
I put it under this category because when ever I put it under the actually category no one answers.. =S
