The original post wasn't talking about being referred to as a "full-blown" girl.
If someone says, "dude, you run like a girl" why is that insulting while telling a girl "you hit like a guy" is considered a compliment? When a guy acts emotional, he's told to stop being acting like a little girl, and I'll bet you it's always done in a derisive manner. The thinking seems to be, crying = girly, girly = bad. How often do you hear a male being complimented for having qualities that society typically associates with females? Yet when females take control, be aggressive, succeed in the business world, they're complimented for being more like a man and given kudos for it. Think about it, having balls is considered a plus for guys AND girls. But female genitalia is used (in various forms) as an insult.
Crying isn't a feminine or masculine action. It's a human one. As a self-proclaimed foodie, I honestly can't fathom how food or drinks can be appropriate for only one gender. And as far as I can tell, piercings are not inherently male or female.
I say do whatever the hell you want and ignore what other people say.
If someone calls you girly, who cares? Girls are awesome.
I was a tomboy growing up, and really, I didn't give a damn if someone said I was too boyish.
