- n. A luxury item. Although commonly referring to an item of significant physical size (e.g. a computer, sports car or big screen television), the term can be applied to any expensive item.
The term is derived from the idea that the price is high (big) and that larger products have physically larger price tags (big-ticket). (Wiktionary)
Migraines were another big-ticket item as well as, of all things, heart attacks.
