Similar to
waterboarding, but not necessarily in the context of torture, depending on the temperature of the coffee.
Usually the mochaboardee will lay flat
on the floor while he or someone else pours a steady stream of coffee over the recipient's face and into the mouth. This practice is particularly effective for making it to work on time after a night of
heavy drinking.
Sid: "Dude, I'm so obnoxiously hung over...what a party
last night, eh?"
Roger: "No doubt, I had to have Glenda put me through a mochaboarding session
this morning, just to make it here
on time..."
