Meatring

A ring of muscle surrounding the opening of the body that lies in the anal area.

A butthole.

Example:
Kraig: "Hey Sharon, can you pass me the salt"
Sharon: "Oh yeah, sure not a problem. But I'll have to warn you I've been itching my meatring for hours and it might be a little gross."
Kraig: "Hahaha. Oh Sharon, we've known eachother for years. You might be a discusting person, but your a strait shooter and I've gotta respect you for that."
Sharon:"We've been friends for years and you know kraig that really means a lot."
