Some examples:
Part of me wants to stay here with you, but another part wants to run away!
You are either: the coolest girl I've ever met OR a total weirdo
You are the coolest girls I've talked to…in the last 15 minutes!
You're either really smart…or a total bimbo!
You could be a model if taller and thiner.
Hug a girl then whisper in her ear I hate u so much.
I just love the way u kiss my neck, it's so sexy I've only known three girls that can do it as equaly good.
One that I use often is hug the girl tightly, and when you can feel that she's into it, playfully push her away and say "Ok... That's all you get." Has worked wonders.
