How do you feel about PDA? (Public Display of Affection)?

I don't mind quick things. hugs, quick kisses, things like that, it's fine. I hate people making out in public, or when I'm with a bunch of friends and two of them are literally holding eachother (or when the guy hugs the girl around the waist and just stays there). I guess holding hands is okay but it's still annoying and distracting when they are friends and I'm trying to talk to one of them. But yeah, making out, carressing, even talking really closely (like looking like they're about to kiss but just talking) annoys me if I am with the people. If it's someone I don't know that I'm just ping by, I just hate making out and feeling up.
