labeling
A word you use to describe someone. It can be mean or nice. If you call someone a fag, a poser, or a nerd, you're labeling them. If you disagree, you're stupid.
You yell, 'You're a fag!' because you failed math. That’s a label.
You say, 'She's a poser,' because she wears pink. That’s just dumb.
You say, 'He’s a nerd,' and you have no idea what that even means.
