2.Also, appropriate when trying to sound innocent while simultaneously swearing because of some misfortune.
This phrase is better when said loudly in a public place, so that one can laugh at the fact that shitindoodle was just said with their friends.
This phrase is usually preceded by a pause so that one can consciously become aware of the misfortune that just occurred.
The main reason that this phrase is so funny is because it is such a stupid thing to say!
Saying this phrase can also be used as a distraction when you are trying to avoid something like, remembering that you owe someone money. Simply say the word and the conversation will go off on a tangent that will allow, for example, your friend who you owe money, to forget about that money momentarily.
