TS:
In this type of scenario, you would need the help of a mature
adult. 
Have a thorough talk with her with another friend ( preferbly a
much older person )
First thing, ask her what does she really wants by doing all those
nonsense.
If you dun like her, tell her in a very harsh way. Say that the
things she is doing, is degrading herself n ruining her reputation
and alot of people around her sees her as a nuisense. With her loud
talking and touchy way, whats the difference between her and the
prostitue from geylang. You will need to be very persistant and
very harsh when saying all that.
Wake some sense into her in a very serious and very harsh way. If
you can't find yourself bear to do it. I dun mind providing the
service. This type of person needs to wake up her mind before she
dig deeper into the grave and ruin herself in future.
If it still dun work, just ask another gal to give a her a tight
slap on the face to wake up her mind ( if you dun wanna use your
own hand ).
She will need to get into real deep sh1t once before she will
realise what she has been doing is a nonsense.
If all these doesn't work, use the ignore button. Ignore her
completely and thoroughly.
Cheers
From old man
