This sudden influx of gross talk about men and her attractiveness thereto is because it's her birthday. That is to say, she's just turned 37, and she's having to confront in cold hard numbers that she's almost 40 with no friends, no spouse, no future prospects, and four-hundred-and-something pounds with half her organs missing and runaway beetus.
Overwhelmed with mortal anxiety, she naturally decides the best way to deal with her mountain of problems is to lie online to unbelieving strangers about men wanting her. If she lies extra hard about hot men wanting her, everyone will be fooled and think she's a hot babe, because she's smarter than us. I for one unreservedly believe everything she's saying. She doesn't have to lose weight to get a man if she just says they want her as she is, and physical attractiveness is her only motive to lose weight, after all.
Of course, a manic phase like this is always the fanfare heralding the "crash and burn" segment of the show. Her birthday has certainly produced some top quality retard behaviour, so let's hope she carries the birthday madness into the lifestyle reinvention/fake diet/meltdown and chimp phase.
ETA: the single funniest thing on that FunGirllll profile is "I'm very ambitious". She's lying about her height, smoking, drug use, all of that, but she's "very ambitious". I suppose death before 40 is an ambition.
