True, but considering it was Bill who said it I don't see the harm in looking for a literal meaning. Personally, I think one of the Stan's had twin boys, and after Author Pines disappeared he went on a cross country search to find him. In 1990 when he went to Gravity Falls, he settled down for a few years and fathered a child...but he couldn't deny his search so he went on looking for his father not knowing the truth.

Or he could just be a dead-beat who happens to be the twins' long lost uncle, or just a dead-beat in general. Gravity Falls baby, anything can happen!
