facebook-exclusive
Someone who chats you only on Facebook and acts like they're too good to speak to you outside of it. They're just using you for likes and comments.
"I'm commenting on your post. Don't expect me to say hi in class.", like it's a big deal.
"You're on Facebook? Let's be friends. I'll never talk to you again.", because they're lazy.
"I'm messaging you. Don't call me. Don't text me. Just like my Facebook post.", because they're a drama queen.
