To care for offspring in a very male way. Often, but not always, accomplished with beer, tv, and half-truths. Successful dadding involves the child being whole and unmarked, clean, fed, in diapers and PJs, and napping/asleep by the time the partner returns from whatever they were doing.
"Our child is fed, bathed, and asleep. Nice dadding!" (Alternate usage: "Our child is still alive and in one piece. Nice dadding!")
