Neither of us are PDA people. But if I get having a good time and a few drinks I like to poke her in her butt. "Goose her" per se and she hates it. Only time I can get a little fresh in public is dancing.
My wife gives me a death stare when I slap her ass, which I do like 5 times a day. She doesn't like my driving either (@npreston is shocked); she says I tailgate and brake too late. Every time she stomps on her imaginary brake pedal, I consider throwing her out of the car while it's moving.
