To cup the elbow of someone in a supportive, friendly manner. Variations of the cup include 'earthquake cup', whereby the elbow is shaken in an earthquake style motion, or 'rock-a-by cup', where the elbow is gently rocked!
The act of cupping one's hands together below one's chin and whisper-yelling the phrase "Cup, Cup, Sir Cup" over and over into one's cupped hands. As a result of completing the task correctly, one shall find that a small tea cup has appeared in the cupped hands. This small tea cup will then tell one a nursery rhyme. Such nursery rhyme shall depict a tube of crescent rolls, which inflate to make an indigo nugget. But this shall only occur, lest the task be maneuvered completely and ultimately correctly. Beware, mutations have been reported upon the first rest after said nursery rhyme.
