Someone who seems to be perfect on the outside, with typically good looking but not the best, who really has nothing to add to the world or has little or no emotion. May also be people who want one thing out of relationships or life.
Dude I can't believe she is dating a barbie (slang) now, she really took a step down.
like a blonde moment, but more general. basically the feeling that what you just said makes you feel plastic, superficial,bimboish, air headed, or princess like.
Erin: Should I wear my pink heels with this or my sparkle hooker heels.
Kelli: its a funeral, stop having a barbie moment.
A barbie-goth is a person who have two sides, a happy side which is barbie and unhappy side which is gothic. So sometimes feels like barbie and dresses cheerful with often wearing pink color. But when feeling down dressing in total black feeling very gothical. So their closet is filled with barbie and gothic cloths.
You'll never know when she shows up wearing pink or black... Well depends what mood she's in... Such a Barbie-goth!
