Red Mackerel 

A obvious mistake made intentionally for your boss to discover. Making your boss feel useful and allowing other mistakes to go unnoticed.

Put a Red Mackerel in that report so we don’t have to redo the whole thing.

holy mackerel 

Holy mackerel is an expression of surprise, astonishment, joy, glee, incrudulity.

Holy mackerel is an ejaculatory term - meaning it occurs rather sudden.

The meaning of the name is an oxymoron, as the mackerel (Atlantic mackerel) is one of the smellier fish and juxtaposed against the Holy, there is nothing Holy about that smell. So in other words its a bit ironic and thus is funny to hear.

Holy Mackerel, Batman is a fav culture classic from the 1960's TV series show Batman that starred Adam West and Burt Ward.

A Roman Catholic. Midly pejorative or humorous. Refers to the former Catholic custom of abstaining from meat on Fridays, and hence eating fish.
