Top definition
The act of repeatedly posting messages, links, photos, or statuses that nobody else particularly cares about on facebook to the point where your posts completely cover everyone else's newsfeed/live feed. This usually results in everybody who is misfortunate enough to be your friend to become extremely irritated with you (as they have a right to be) and hide you from their newsfeed.

Oh I know! Her posts are blowing up newsfeed!
