The act of sending emails before you have attached the files or finished writing the email. This typically occurs when someone has had too much coffee, is sending out a lot of emails in a row, or feels too much excitement regarding the email. This happens in texting as well.
Lisa was confused when her email from Sara arrived without the attachment but Sara explained that she got SEND HAPPY and sent the email too soon.
