Here's a topic that I've heard women talk about a lot. Determining the future with a significant other based on how well they kiss! A judgement early on, and the relationship is doomed from the get-go. Maybe they just had a bad night/day and poof, regardless - that's the end!
One of the first questions the girls ask their friend after a date is, "Well, how was it? Is he a good kisser?" Guys ask different questions from a friend after a date, and I'm sure you know what they are. :)
Women, are you guilty?
