new to group. What is a deadbeat dad?

it is usually somebody who has been flailed to a ninch of their life by
being accused of being insensitive to their child's needs while in fact
they are struggling to put food on the table for themselves whilest
being commanded to make good sized (for their incomes) support payments.

I typically refer to it as "Beat Dad Dead" in my affidavits, and yes,
the ex has thrown that term around to everybody, kids included.
