yak rabbit 

The combination of the commonly used expression "rabbit hole" with the expression "to shave a yak".

Our Scrum Master on our recent sprint really knows how to make "yak rabbit" soup, he carried on and on about that one component in the build until it seemed like we were trying to invent cold fusion technology coupled with loss-less solar energy technology but found no definitive solution or end goal in sight.
