perficle
The act of ones elbow and arm being able to be perfectly placed and rested upon one another beings shoulder. Because they are the correct height they are able to be used as a perfect arm-rest.
As the purple power ranger examined the situation further she noticed that the savage david was 'perficle' for a nice arm rest after a long night of hard core drinking of jack daniels tenneesee whiskey concocted with vanilla crown and root beer and dominos pizza.
