What is Boner, I've Got A ... A Dingo Couldn't Bite Through?
1.
Used to describe an erection so hard that, if given the chance, a dingo (Australia's native wild dog) would not be able to damage it.
Given the silliness of the statement, it's usually used to describe a non-sexual situation that a man would nonetheless enjoy very much, such as a sporting event.
When the Cats won the 2007 AFL Grand Final, for the next week I had a boner so hard a dingo couldn't have bitten through it. (boner, I've got a ... a dingo couldn't bite through - gotta use the original here)
