So much of a dude s/he changed his/her name to a girls name and has morphed his/her body to be feminine as possible. Whether or not somebody is 'trans' at that point or wants to be called a guy is kinda not important.
There was actually somebody arguing the other day about how Bridget from guilty gear isn't trans and was just a feminine boy trap. When Bridget was made as a character back before people liked to draw distinctions between 'gay-femboy-crossdressers' and trannies, nobody made autistic categories because there was less of a 'mental illness' stigma about trans people back then and more of a 'she's a dude, GAY!' sorta of stigma, making those two categories as 'exactly the same thing, save a technicality'.
If you look up the meaning of the meme trap, you'll find that it was started in the early 2000s on Something Awful and Newgrounds and it refereed to 'transsexuals and gay transvestites who pass entirely as women and try to initiate sexual activities with men without first disclaiming their sexual/gender peculiarity. Or in other words, "don't let the trannies trap you, lololol".
That said, the is a distinction between femboy and these twink-crossovers people here have been going nuts over. A femboy doesn't have to be gay or straight or even have any sort of highly sexualized bent, they just like girly attributes. Similar to a more mainstream crossdressers (most crossdressers are straight, believe it or not). Whereas the twink-cross dressers IRL here are camwhores, and in 2D are 'draw a girl, call it a boy' to the point most of them are just flat-chested dick-girls.
