No, these are not mommy-jackers out to remind us of the labors of parenting. These are parent posters of a different breed, often aiming for the shock-and-laugh effect.

Son: Comment when and where we first met!

Friend: 7^th grade Science

Dad: Nine months before you were born. I brought you on a date and you went home with your mother.

They also seem to have mastered the fine art of embarrassment. Cite: photos of little princess’s head in the potty, or toddler son reading last month's issue of Playboy. While embarrassing perhaps to their subjects, these posts are good for a laugh and make dads not technologically-savvy enough for Facebook look just a little bit better.

Yet, Facebook fathers are not always taken so lightheartedly:

Dad: Just found out McDonalds has a playpen. Put Finn in last night, plan on picking him up Monday.

Mom friend: Please tell me you have Finn with you?

Mom friend: Not funny Steve, is Finn okay?

"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.
