A derogatory name for a Starbucks employee or Starbucks junky.
Coined from how they make you order a double espresso.

a dark sinister phrase uttered when something goes your way. A play on words with the religious "hallelujah". Best when used around religious zealots.

When making a shot of espresso, one tries to remove the portafilter while pressure is still being applied to the coffee. The resulting expulsion of pressure causes hot water, coffee, and coffee grounds to shoot out in multiple directions. Mimicking a sneeze.
