Im not shure whether this Thread is in the right place, plz correct me if its not

Im not going to clubs regulary,
but when i do i often get into a specific situation i really dont know to handle (im still a wanna-be-PUA btw):

I often dont try to game a hole evening, especially when i went to club only to dance or curing a bad mood or something; but when i had been on dance floor a long time while only tangential dancing with women i dont show real interest in, it often happens that a female member of a set seems talking to the others in a amused way, pointing at me and then approaching me with something short like "you are/seem to be the cutest/coolest guy here" (happened 3 to 5 times already).
This is the point i cant interpret: actually i dont know whether she wants to make fun of me or it should be a kind of opener or something. I have to admit that im not the biggest guy and i also have a younger appearance than i really am (20). When i where at school i made the experience that the behavior of girls in my direction often was affected by this attitude in a similar, but negative way. So i never know whether its a IOI, a shit-test or just something mean when it occurs in club now .
Another problem: also if im having a vague idea how to react, i often cant realize it because its to loud to talk without shouting in her ear and i dont have the strongest vocal folds^^
Shure ivegot some ideas but i wanna discuss them first before trying them out next time:

First:
*Intend to dont understand her because of the music (sometimes its not even fooling her xD) and then try to separate her and lead her to some less noisy place.
*OR: Cocky smile, maybe a short dance with her, wait for the right moment to approach her on the bar.
Second:
*Just ignore her comment and try to start a conversation over something off topic.
*Kind of neg her about her strange approach (something like: "You really tend to prejudge a guys attitude, do you?")
*Ask her what exactly she meant (Not word by word, maybe in arrogant-ironic way like "How can you already now that im the coolest guy here ")

How you would read this kind of approach?
What do you think about the possible reactions i want to try out?
Are there any other reactions you would suggest?

When i get into another situation like this, i will ofc test something and post a field report (if there remains something to discuss about).

What's your height and weight?

I was used to be extremely small in school (almost smallest person until 9th grade, girls included) so its obviously that some of them made fun about it.

But now im slightly bigger than 170 cm and my weight should be of course more than 50 kg or so (didnt test my weight for some time)
=> obviously not the smallest guy in club, but still small, thin, but not extremely skinny

Your height isn't too bad. You could gain a bit of weight. I might suggest lifting and implement a good diet.

That said it could be anything besides your frame getting you attention. But at least it's attention, whether it be good or bad. You should still be cocky and start a conversation right off the bat. Out of all the alternatives you listed, the last one is your best bet. Your small frame might lead girls to suggest you aren't all that dominant, so surprise them with some dominance and confidence of your own. A guy might get PREJUDGED on his frame, but a guy will always get JUDGED on his attitude.

Also don't be afraid to yell in a girl's ear at the club. It's a good excuse for touching her, anyway.
