A girl sent this to me and it got me going! It was a girl I had hooked up with so I was thinking,
oh crap whats she about to ask me here! and my heart was actually beating harder lol......
So I then decided to forward it to a few girls and it worked a charm. Including a girl who hasnt spoken to me in about 4 months, she replied in 2 minutes.
I sent it to a few girls here were my results:
HB10: Screw you ___! my heart was pounding

(as much as it may seem like this isnt succes, it was... She hadnt spoken to me in 4 months and after this we began texting again)
HB7: hahahahahhahahaah you are an idiot! I was reading this thinking what the hell is he on! LOL
HB9: loooool had me going! you are crazy
HB9: I am a coke girl

I hope that is ok with you
None of them actually answered the question... So its clearly not about the question, but the emotions they go through! If they dont answer, you can text back demanding the answer "coke or lemonade? I gotta see if youre my type!"

and go from there!
This is it.
Hey! I need to ask you something that has kept me sleepless and I want you to be totally honest with me. It might be awkward between us after this but I have to know how you feel. I have kept this in my mind for a while now but I think it's finally time I'll be straight up and just confront you.... I hope this doesn't ruin the relationship we already have. I just need to know and I don't see any other way I could get over this. It wouldn't be fair on me if I don't get an answer. I want you to tell me truthfully, no matter how harsh it is. I just want your honest opinion... Do you like coke or lemonade?
The beauty is, I had the text sent to me so I only had to forward it. If you wanna use it you'll have to type it up yourselves

(or copy paste from here somehow, I dont have a smart phone so I dunno if you can

)
Extra suggestion...
If you already have an inside joke with a girl of some-sort, you could personalize the final question bit to something else so she will enjoy it even more.
My friend, this is fucking brilliant but I would recommend EVERYONE to use a different question, as girls these days may google 'coke or lemonade text' or some other variation and guess who's result #1... careful boys!
