Doing your chores last minute and quickly like a ninja before either one or both of your parents arrive home. Or to pretend that you did your chores when they left to go out but instead you decided to hold it off and be lazy till you had no choice but be quick like a ninja to finish off them chores and thats why its called ninja chores.
