The act of posting or commenting on an unflattering Facebook photo, usually resulting in its broadcast across the News Feeds of mutual friends and subsequent spread across Facebook. This is typically done with the intent to harm, defame and/or embarrass the individuals depicted in said photo.
Putnam untagged all the photos from last week's party, but we feedbombed the shit out the one of him crawling out the freezer.

Get the feedbomb mug.
When someone you thought was cool likes something bigoted, ignorant or otherwise heinous on Facebook and you see it in your feed, so you start liking as many things as possible that refute said heinous like, hoping the once-cool person will see your likes in his/her feed and perhaps take a moment to consider whether he/she might in fact be a thoughtless moron.
Disillusioned Girl: Ugh, that smoking' hot guy I met on vacation liked some idiotic "Straight Pride" meme on FB. Dream officially shattered.

Disillusioned Girl's Friend: Just feedbomb the shit out of him with every rainbow-colored thing you can find.
