Beware, this is a dangerous path! Harnessing such powerful black magick is not for weak minded! Too much and it will corrupt you and you will become ... TRANS! I too once started out with thigh highs and spinning skirts, but I wasn't strong enough, Arch Linux was too much for me to handle, now you have been warned!
I really hope this is a joke because the egg stuff can be quite hurtful to femboys and GNC people, it's often used against them to say that they're just trans girls in-denial (especially for the ones who took feminizing hormones). Just for clarity to call a Femboy a girl when they don't want it, is misgendering, calling them an egg is extremely disrespectful and invalidates their gender identity.
I know this might've been a joke but all too often these kinds of things are said in contexts where it isn't a joke and comes off as hurtful. Also it's often very hard for people to tell because one person may say it as a joke but another person may mean it whole heatedly.
