For women that line is not fine or invisible at all. We have been dealing with this since puberty and can tell the difference right away.
If you are looking at a woman and thinking, "Damn. I'd like to motorboat that," she will pick up on it and think you are a creep. If you look and think, "Cute. What time are the Skins playing tonight again...?" you are simply noticing and not creepy.
Yea it's kind of hard to explain. I've dealt with it forever. It's just this.......look they give you. Almost like you can see their though process. It's either "That's a fine piece right therrr" or "Hey, this is a pretty girl. I'm gonna try and buy her a drink and see how conversation flows".
I guess, the more casual you are in your approach, usually the less creepy it seems.
