Blame it on Dyslexia
Sorry, I’ve got another name for a half-gallon of flavored water that retails for $6 at Target (it actually comes in an 8-pack).
How about, “Spendthrift?”
I’m gonna guess that the marketing folks who came up with “spindrift” are all under 30 years old and/or don’t have kids.
Then again, that’s probably their target market . . .
P.S.: Maybe they were trying to evoke “Driftless,” an area in southeastern Minnesota and southwestern Wisconsin that was skipped by the glaciers.
