So sweet talking = spouting cheesball sissy romance lines aye?
Alright. I guess the aim of sweet-talking is to so-called "score" with the girl or guy, i.e make a good impression, get to know them better and most importantly; to keep the attraction going.
I suppose how anyone should sweettalk anyone else (romatically) is to not be TOO EAGER. You have to be Nice as in conventional, but don't be a sucker for niceties, and do not be sissy like or overeager. You must have an air of gentility about you combined with a feeling of "not caring" about them. Its not totally about what you say as in exactly what kind of words you use, its about how u say it.
i.e. What you guys are saying:
m: Bond... John Bond...
f: oooooookayyyyyyyyyy... next!
or
m: something about what your daddy is a robber...
f:wtf?
m" yeah ur daddy is a robber coz.. he stole the star and implanted them into your eyes...
*LOSE*
-What i am saying
f: friday is not good for me, i have something on,saturday also am busy.
M: Perhaps next time, if you you share mutual liking of company, you might give me a call then?
f: Sure, i tell you what, how about this coming week?
M: Exams this week heh, even my feelings for you are not that intense that i must forgo mugging time

f: Then the week after your exams la!
*SCORE*
