Necessary, Mom? (From Mommyish.com)

"Mommyjacking: The art of single-handedly ruining your friends' Facebook posts by mentioning your child completely out of the blue and steering the conversation towards parenting."

It's a craze that has swept Facebook–out of nowhere moms (and inevitably dads) will swoop down on your latest status and find a way to turn it around with a quick, often snide remark about parenting.

Sarah: “So tired, been such a long day.”

Mommyjacker: “Try having children, then you’ll know the real meaning of tired!”

Sarah is just one of many falling victim to the increasing cult of Mommyjackers, as more and more users log on to see their personal posts swarmed by unwanted advice and tidbits from their friends with children.

There are different levels of jackers, ranging from the classic mom who truly believes that seeing photos of her ultrasound will make your day to the ones who will gladly trample over your good news with their own:

Kathleen is engaged.

Mommyjacker: “Congrats! Me and Matthew found out we’re having another baby today!”

No Mommies, just no…

Be warned, New York: the next time you log on to tell the world about your good news, bad day or aching back, a mommy may just be lurking nearby ready to hi-jack the hell out of your post.
