Definition: A milder version of POS; sometimes refers to a piece of junk, but may also used as an exclamation towards someone else, i.e., in online gaming, when someone sneaks up behind you and kills your character, you might type, POC! Example
You may have noticed that your lips turn purple or blue in the cold, or you may have seen a baby, an elderly person or someone else with bluish or purplish lips. In many cases, this type is caused by cyanosis, which is a discoloration of a part of the body resulting from a lack of oxygen in the blood.
Lack of blood flow makes the penis and testicles turn purple and they can die in as little as two hours or less if the blood flow is blocked off enough. Go straight in for help, you could lose your penis and testicles to gangrene if no help when the blood flow is cut off.
