What is the term for a 'decoy' feature or intentional bug? [closed]

Question

I have forgotten a slang programming term. This thing is an intentional bug or a decoy feature used as a distraction. An example usage, "Hey Bob, QA is doing a review today. Put a $THING into the module so they actually have a problem to find".

This can be used negatively, to have a very obvious intentional flaw to discover as a distraction from a real problem.

This can also be used positively. Its like how you always let rescue dogs 'find' a victim when searching a disaster area. It can also be used to verify that a QA process is actually catching flaws.

What is the term I am looking for?
