It is a primarily British language construct that means simply they "like/are attracted to" the other person. A rough synonym would be "care for". Also used for inanimate objects ("I really fancy a good filet Mignon with onions". I don't fancy the architecture of this place, though").
I'm a guy so I should be able to answer this. If he trusts that you won't tell anybody who he fancys, but he STILL won't tell you, there's probably a good chance that he fancys you, he's just shy about it. Either that or he doesn't want to tell ANYBODY who he fancys, for risk of getting rejected or made fun of by the girl that he fancys. I'm not sure if this helps or not but there you go.
it fancys you.
You may want to explore why you fancy a person who calls you fat. Mean is mean; find someone who will be kind to you to fancy. If you are "fat", or physically unhealthy, there is no greater time than today to begin a healthier lifestyle. Value yourself and take care of your life.
it means the said boy fancys you and wants to be around you without you knowing.
my dad!
well yes, why would she bother, but is does not mean she fancys you romantically. She might be a nice girl being helpful.
