Bus Boner 

A Bus Boner is an erection that one gets while riding the bus. It is usually caused by the combination of fatigue, warmth, and the vibrations of the vehicle. Similar occurrences have also been reported in mini-vans and tour boats.

Michael was afraid that when he stood up to get off at his stop everyone would see his bus boner.

Denim Boner 

A phenomenon which only occurs once an individual wears jeans. It is most commonly used to describe the lump or bulge which forms on the around the zipper/crotch area when sitting down. Any attempt to 'squash' the said boner may result in making the situation even more awkward, leading most to ignore it and hope nobody else notices, much like when you pop a real boner on the train and can't get it to go down.

Fred noticed he was rocking a denim boner but when he tried to push it down, everyone on the train started to stare.

hatey boner 

A long, rather unusually strong, raging hate for something that threatens to explode at any time.

I want to like "Fringe," but my hatey boner for J. J. Abrams just won't go away.
