The true definition of this was told to me a while back by a friend of mine, apparently I'd been getting it very wrong before. I'll try and quote her

"It starts around 7 or 8 pm, in the intimate little eaterie you booked earlier. Good food, some wine, perhaps some champagne.
Next, onto a club, some dancing and maybe some more drink. An by dancing I mean YOU dance with ME. It does not mean take me out to a club and stand at the bar getting too drunk to walk whilst leering at every other woman in the place.
After that it's back to either your place or mine, if you're lucky, where you can ply me with some more drink, some good music and then, after a while, I just might let you start what you consider to be foreplay.
Oh, and LEARN TO KISS"
