A ridiculous non-word made up by marketing people who think the term "e-mail" is inadequate to describe the explosive excitement of their mass e-mails.
Also "eblast" or "e-mail blast"
If we send out an e-blast, the widget will literally fly off the shelves!
The online version of being 'put on blast' by a friend who wants to embarrass you. It occurs when embarrassing personal affairs are made public through one of your social networking profiles, usually perpetrated by the wild and reckless stoner friend who will never be bothered with looking for a job.
My friend put me on e-blast before I could remove his post from my Facebook page. Now, my coworkers have seen that...ahem...photo, and my mom keeps asking me about my 'fetish'.
