Let's get straigth to the point. I met this girl, potentially a nice one (maybe you can see where this is going), online and she had the strangest request I've ever heard: she wanted me to fart on her friend's face. Said she won't trust me if I don't, or something like that. Right now I'm thinking she wants that just to embarrass me, for whatever reason. Then I asked her what she would be willing to do to prove that her intention isn't only to embarrass me, and she asked me what I want her to do. So I come to you, my fellow gamers and experts in female behaviour, to suggest any good actions. Should I even try to get further with this? Is there something she could do to prove herself? Anything else?

(You should also note that I don't live in the US so there could be slight cultural differences. Still living in a western, industrialized country though. No, this is not normal here, it's still very odd.)

Also, wtf.

PS: I was just about to post this in NSFW but a lot of the threads there went quite further than this so I decided to post this here anyway.
