When a chastity cage is incorrectly drawn on a penis, rendering it useless for its intended purpose. Generally, this is tagged because the base ring is missing, so in real life, the device would most likely simply fall off, and even if it somehow stayed on, it would not be nearly as effective at preventing an erection. Occasionally, this is tagged because the base ring is drawn entirely in front of the balls, which would be just as useless as not having a base ring at all.
