insta-dad 

Ring up the late night T.V commercial's to get an 'insta-dad' delivered to your door. Insta-Dad is great for fulfilling the gap left by an incompetent or missing dad and is a great present for Christmas. Insta-dad never gets angry at you for smoking weed and does your homework at the same time as cooking dinner. Comes with 30 Day Money Back Guarantee.
Whats it to you?'s defintion is also quite acceptable and funny.

"Thanks Insta-dad!"

A man "who has no kids" that dates a woman with kids.

She told me she had a kid. I don't want to become an Instadaddy.

Instadad 

*Noun

Someone who is immediately placed into the social media roll of a child who is not their own. They do not mind such attention as they have regressed from their werewolf like facial

and eye slant complexion. Now awarded with such a rushed opportunity the instadad defies the odds and checks all boxes to achieve.

He became an instadad over night.
