no need weird tactics and stunts to ask someone out, unless the girl is some bimbo dumb enough to fall for it. not that it's a bad thing, im just saying, maybe your type.
you just need balls, looks and some personality.
just ask her if she wants to go out. if you got a time or place i.e. a PLAN, better.
if she refuses it is not because of your tactic/strategy/gimmick etc. the reason for rejection is something we are too proud to admit: she just doesnt like YOU. that is her preference. you can't change that, or change her, you can only change yourself if you want to.
the other possibility of course is that she is some dumb bimbo who doesnt know what she wants.
or maybe you can use the stunts to compensate for your lack of guts, maybe it will work. but fortune favours the brave, and you reap what you sow. if you don't want to spare the effort then aim lower.
