Public displays of affection are gross...

[Cream of Caulk]

I agree, I think it's so gross. I've only known 2 couple personally that do this and they tend to be needy. But I also knew one behind the scenes and they fought like cat's and dogs but they put on the PDA show in front of people so it's doesn't usually mean they are in love. Maybe that's why we are grossed out by it because our subconscious know it's fake. They ended up getting divorced becase she was sucking walmart employee dick in dark parking lots.
