This is probably my favorite VDGG song, they can be surprisingly catchy at times. Anyway, I think it's about a person who's mean and violent, so nobody wants to be with them. The whole "your mother gave birth to you" part is, I guess, about him being abandoned by his family for his ways. And the rest after that is about him regretting all this and wanting people to love him.
