What is the word for very small bad luck or mishap or accident? An example would be like when you get a gravy stain on your shirt while having breakfast. Another example could be, a funny and awkward, you accidentally farted in public. Or maybe your phone crashed when you needed it or the cap/lid accidently falls off and you ended ruining you dish with awful amount of salt.
I had a _________ today when I accidentally spilled coffee over me.
