Diesel Boner

An enormous erection provoked by the sound of a Diesel engine. Usually reaching its peak upon hearing the compressor surge. Pointing slightly to the left is a key sign to look for.

It was inevitable that Tyler would end up with a diesel boner while at work after hearing the big Ford leave the parking lot.

shame boner

(n.) an erection that invokes a feeling of self-hatred. It arises during an event that is naturally sexually arousing, despite it being a violation of one's moral standard.

Comfort Boner

An erection caused by the mere complacency with ones friend or partner, but not necessarily in any sexual way.

Jennypie noticed that her bf has an erection 80% of the time they're together, and he said it's because "I just get a comfort boner when I get comfortable (i.e. chilling on the couch, etc) with you."

boner a dingo couldn't bite through

Used to describe an erection so hard that even a dingo (Australia's native wild dog) couldn't damage it.

Given the silliness of the expression, it's usually used to describe extreme enjoyment of an activity not related to sex, such as a sporting triumph.

When the Cats won the 2007 AFL Grand Final, I had a boner a dingo couldn't bite through for the next week.
