The act of erecting ones penis due to extreme wind activity.
i.e. Skydiving, motorcycle riding, and even a really windy day can all lead to the erection of a wind boner.

The feeling you get when you are driving and you drop quickly over a hill. Can also be used to describe the rush you can feel in your stomach/groin anytime you drop quickly such as on a rollercoaster.
The little hill back there gave me a windboner. I love that shit, let's go faster next time.
