I've just come up with this now so i haven't tested this yet.
This is good to use if you're texting or calling a girl you've number closed the night b4.
Before you number close:
Through into the conversation some talk about movies. If they mension a movie they really love tell them you've never seen it (even if you have). She'll say "Oh you just have to see it!..."
Continue your conversation as normal.
The next day:
Text her and ask her what the name of that movie was?
She'll text back with the name.
Text again and say "i'll let you know in a couple of hours if your taste in movies is any good.

"
Watch the movie, or don't it's up to you.
Text her back in a couple of hours and say "it was the worst movie i've ever seen" (or something like that). Say she owes you those 2 hours of your life back and that you're taking them off her.
Then ask her out to dinner
Let me know if ya like it / hate it / how you would adapt it to suit your personal style.
