1. A word used to describe what you can't at the moment, usually for an idea or concept that is not easily described. Usually preceded by a hesitation, used mostly in sentences containing possessive nouns, where an entity would have an intangible object whose intentions need to be explained, or in situations where several words would be needed to describe the object but where the speaker does not feel compelled enough or immediately
able to finish the description.
2. Used as a substitution word for shared ideas that need no
explanation, or in situations which have inferred complications or details that do not want
explanation, for reasons such as speaker-desired lackadaisical ambiguity, or purposeful hesitation.

"Why didn't she tell you the
truth?"
"Oh you know... ever since the breakup she's been... you know... and that sort of thingstuff."
