When someone posts something on a social-networking sight such as Twitter or Facebook, saying something mean with out using someone's name, but you know it's about you.
Taylor's Tweet: I cannot stand you. You are so annoying!
Jessica talking: Oh my gosh. That post is obviously about me.
The only reason she bitch-me posted it with out a name is so no one else knows how mean she can be.
Carly: Yeah I so agree. I'm just going to ignore Taylor for now. See how she likes it.
