e-holla
A rude reply to an email. Like when you're too lazy to write a full sentence and just yell at the screen.
Hey, you sent me an email? I'm too busy to read it. I'll just scream at you instead.
Your email was long. I replied with 'I'm not done yet, but I'm here.'
He emailed me a question. I responded with 'What? Are you high?'
