To unexpectedly stumble across something that you`re looking for. A gloriously lucky moment.

Something that is extremely valuable, coveted, or held in high regard.

This is evidenced by the fact of gold is very rare, valuable, and pleasing to the eye. Also, a baby is treated as being just as valuable, rare, and with the creepy way and frequency that people (especially women) stare at them perhaps more valuable. The combined effects of these infers an exponential effect.

An insult, meaning "gay". Like that saying "silence is golden" and then that other saying "when there is silence a gay baby is born" so telling someone they are a golden baby is basicly calling them gay.

When your dick gets so hard it almost seems to glow. Dicks create babies so when you dick is amazingly hard you are going to attempt making a "golden baby" with your amazingly hard ass "golden" dick.

Your baby that you love and "glows" when you look at him/her.
