Hate to sound big-headed but I've had the kind of attention OP speaks of. On nights out especially, when the girls have had a dose of liquid confidence.
In such a case as that, it's much worse than them standing near me and "accidentally" brushing against me or walking into me. They often come up to me, bold as brass, and start flirting. The giggling that ensues from their gurrrllzzz is annoying as fuark. It might sound like such attention would be a good thing, but it isn't, because the vast majority of girls are rubbish at pulling. They aren't seductive or sensual about it at all, instead they come at you with over-zealous teasing and the kind of banter their "alpha" guy-friends have probably used on them.
Personally, I think girls hype up the hot guys that they see. Similar to how men convince themselves that certain girls are "special" and worthy of extra attention and fawning just because they happen to be hot. It's just that, hype. Nothing more. I fall short of most of their expectations in the sense that I'm not some modern day cassanova or that I can **** like a god just because I've been born with a symmetrical face and well-proportioned features. The problem with shallow people is not that they favour people with good-looks, but because they let those looks influence their opinion and image of that person to such a point that it's nowhere near the actual truth.
