Used at McDonald’s to describe someone that is very
stupid and unskilled. Cooking bacon is the simplest
thing to do, and “
cook good bacon” is code word for someone that is stupid and can only do the most simple chores. It’s meant as a very derogatory statement.
Standing in front of the new person, the manager told her that she
cook good bacon and the new person
said thank you, not knowing it was a dig at her for being stupid.
