E-Snob
An E-snob is someone who acts like they're too good for you because they're online all the time and don't bother to reply when you send them a message. They're like the rich kid who ignores you at lunch just because they have better things to do.
'Hey, I sent you a message 10 times!' 'I know, I'm just too cool to reply.'
'You're not even on my list!' 'I'm too good for you!'
'I'm busy being an E-snob, okay?'
