Sleepy Dick Syndrome (SDS) is a medical condition caused by pinching of the specific nerves depriving blood to a man's genitals. Common sensations include numbness, tingling, and paranoia causing you to check if it is still attached to your body. Recommended treatments include slapping it, telling it to wake up (politely), tomato sauce, and jiggling it a little bit.
