Saganboner 

A great love for all things astronomical and scientific in nature, similar to that of the late Carl Sagan.

One Guy: We are all starstuff
Other Guy: Oh man, I've got such a Saganboner

Saxaboner 

When you play the saxophone so hard you get a boner

Dude last night I got a huge saxaboner
