A male weightlifter or bodybuilder whose oversized pectorals, a symbol of strength, dominate his general physique and become the focal attention so much that it becomes lewd. Often accompanied by large nipples that thrust out when bare, or poke out when in a shirt. Often used for ridicule or muscle humiliation scenes.
