Half caff 

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.

Half Caff 

When a man's penis is not quite a full boner yet not quite limp either. Essentially the Goldilocks zone of penial stiffness.

Do you see that bulge in that man's pants? He must have the half caff.

Half caff 

Trading half of something you have with half of what another person has.

Person1: "Hey, let's half caff!! Can I have half of your cookie?"
Person2: "Sure, if you give me half of your drink!"
Person1: "it's a half caff!!"

Half past caffeine 

Approximately half an hour after caffeine o'clock, at which point a visit to the bathroom is commonly required.

Often a forgotten consequence of caffeine o'clock, half past caffeine tends to become pressingly apparent to the victim at a most inconvenient time.

Supervisor: Where do you think you're going? You just had your coffee break half an hour ago!

Victim: Yes, which makes it half past caffeine! Oh god!
