When my friend, Nick, ordered a "grande mocha half caff two pumps no whip" today, the barista knew exactly what he was talking about and offered to give him extra foam!
A mix of coffee that is half caffeinated and half decaf, which is primarily consumed by middle-aged women when they are not drinking white-wine spritzers.
"I'll have half caff, please," said the 35-year-old cat lady with bags under her eyes, to the strapping young barista.
