"Dude, that's so meta."

Meta is a prefix, derived from ancient Greek, used to indicate concurrency and reference.  Metadata is included with your data and describes aspects of the data while remaining separate from the data itself.

"Yo, bro, that's gross."

Gross is a word descended from Latin, through French, and into Middle English that originally meant large.  In current English "gross" is no longer used this way and instead means a collection of twelve dozen (144) items.
