Is there such a thing as a "triple entendre"? If so, the word "consumption" would pose one. An outdated definition of consumption is truly a disease, the colloquialism for tuberculosis around the time my great-grandmother succumbed to it in the early 1950s.
On the other hand, the two other meanings that come to mind for me are quite "au courant" (French for "up-to-date"): one implying the intake of food, the other implying purchasing behaviors and patterns.
It is the latter of these three meanings which serves as the subject of "Spend Shift: How the Post-Crisis Values Revolution is Changing the Way we Buy, Sell and Live," by consumerism expert John Gerzema and Pulitzer-Prize winner Michael D’Antonio.
