My bf likes Rainbow Dash but only because he plays this cult British zombie game online that has firebombs that are shaped like her. He gets three at a time and uses them to blow up zombies. I find it quite funny but if it was Cotton Candy obviously I would not be impressed! He took a screen shot for me last night, will post if he gets around to sending it to me.
We both have hobbies and tend to do our own things, but we don't spend a lot of money, so think he likes that I have an interesting hobby but would probably be a bit put off by some of my more valuable ponies.
