An irate little man that pops out of your butthole and screams at you to stop grunting and wiping your ass so hard. He also punishes you for eating Mcdonalds everyday and drinking a case of beer every night.

Hemorrhoids are swollen veins in the anal canal. This common problem can be painful, but it's usually not serious.

Veins can swell inside the anal canal to form internal hemorrhoids. Or they can swell near the opening of the anus to form external hemorrhoids. You can have both types at the same time. The symptoms and treatment depend on which type you have.

Too much pressure on the veins in the pelvic and rectal area causes hemorrhoids.

Normally, tissue inside the anus fills with blood to help control bowel movements. If you strain or sit on the toilet a long time to move stool, the increased pressure causes the veins in this tissue to swell and stretch. This can cause hemorrhoids.
