Coffee Dodger
An individual in your home or office who avoids making a new pot of coffee by filling their cup just enough to leave a minimal amount behind. The remaining dregs comprise roughly 1/4 to 2/3 of a standard cup, a magic threshold that keeps the Coffee Dodger from feeling obligated to brew a new batch.
"I was late for a meeting because some coffee dodger left a couple of sips in the pot and I had to brew a new one."
