An attention-seeking act where a person uses facebook to announce something of significant personal importance such as an engagement, pregnancy or even the death of a loved one.

In many cases people will deliberately withhold the news in conversations with friends so as to not reduce the sensationalism of their announcement.

This is totally gay.
Facebook: **** **** is engaged to ***** ******
Sophie: OMG congrats xxxxx
Jenny:OMGZ that's soooo great xxx
Me: How come you didn't mention that yesterday when we spent the day together? Facebombing?
