In my uninformed speculation, it goes like this:  Fatty has a hobby of playing around with dudes online; she likes the positive attention and she likes to indulge in the fantasy of being attractive to them.  It's essentially roleplaying, and she is conscious of that...  most of the time.  It's a bit sick, and she knows that too.  But once in a while she lets herself slip into thinking that maaaaybe the man of the moment will be the prince who will see through her ugly shell to the beautiful person that she imagines is inside herself (somewhere, swimming around inside her giant roomy torso that's full of space because it's so fat hm yes).  So she gets her hopes up and meets the guy and is slapped back to earth.  Then maybe she stops doing any of this for a while, before she finally forgets again how painful it was to get rejected and gets to thinking that maybe it would be fun to start flirting around online again. If that's how it goes, then it's a sick, self-abusing, other-abusing practice (like so many things fatties do), but not something that is so nonsensical that it couldn't even be real.  I mean obviously this is real; there are endless stories about it after all.  It must make sense somehow...
