1.) A stand-in all-purpose term for BORING DETAILS in a story.

2.) A (mumbled) substitution for some bit of information as a DODGE or a FAKE-OUT or as if the proper answer were too burdensome to speak. Used to avoid answering; or, as in "WHATYAMACALLIT" or "WHOSIT".

3.) An all-purpose REPLACEMENT for any WORD or NAME or such that is tacitly understood by those communicating. It is used to avoid actually having to say the "thing" that might not be cool for others to hear or know about i.e., in telephone conversations of a sensitive nature, in uncomfortably crowded places like elevator or subway.

4.) Similar to Hawaiian slang: "DA KINE" meaning practically anything for (lazy) convenience and loaded implicitly by context.
