Uptight, reserved, unable to let loose. The epitome of anal-retentive. Like a bag with a drawstring pulled tight.

That round orifice that comes out of your anus and helps you take a dump. The entrance to the asshole.
A sixteen-year old girl woke up tied to a couch one morning. She did not know her surroundings. She heard someone from behind her walk up. She felt her butt being spread open by hands, and she felt something like a cucumber being inserted inside of her. It started pounding at her faster and faster. This virgin's sphincter felt nothing but pain as her rapist tore her with his cock. She looked up to see that she was being assfucked by an old man she didn't even recognize. The virgin started screaming from the pain as she was being pounded faster, and she was smacked on her right buttcheek. She stopped screaming, and found out she actually enjoyed it...

A viral infestation of asshole behavior. Extremely ubiquitous. No known cure but sure working on one.
