Going to Be One of Those Days

A character gets up in the morning and soon finds something bad has happened- or is about to happen to them. They respond with some variation of: "Sigh... I guess it's going to be one of those days."

This is typically what Deadpan Snarkers will do when normal people would have an Oh Crap moment. In action-orientated series, it will often overlap with Casual Danger Dialog.

May overlap with This Is Gonna Suck. See also Here We Go Again.

Examples of Going to Be One of Those Days include:

Live Action TV

In Tru Calling, each Groundhog Day Loop was "one of those days".
