Dad boner

A man, not necessarily a father, with an intense love for a surtain interest or thing.

Could be compared to how a child likes to show their toys to everyone or a child seeing something for the first time.

It could be looking at trains driving by, big cars or thunderstorms.

Often used to describe people in the clips of "Your moms house" podcast.

*Points to a man clapping his hands as the train drives by*
- Omg Jenny, that guy has such a dad boner for trains.
