hint water

A water beverage advertised as being flavored, yet actually contains very little flavoring. Basically a seltzer water without the carbonation. Fits into the category of "new age" drinks that move away from traditional sodas/pops.

"This hint water tastes just like seltzer!"

"There's a new kind of hint water, it's grape flavored."
"I stopped drinking soda and now I drink hint water."
