rusty ring donut 

The brown circle around your cornhole. Many mistake it as shit stains, but no need to worry, it is natural. Push your finger in and find the secret filling inside. The rusty ring donut is also the breakfast choice of many queers and prison inmates.

Mrs. Weathers who is the ultimate cunt-slut stated that she loves the taste of a warm creamy rusty ring donut when she has a nice hot Dickin's Cider.

Rusty o-ring 

When a man fucks a person in the ass then wipes the head on the partner's lips as when applying lipstick.

After a jack hammering anal session I turned her around and gave her a generous rusty o-ring just before she had to work.

Ring Rust 

A veteran of the anal arts, but is out of practice after a long layoff.

I asked my boyfriend to only use one finger in my asshole today. I'm not ready for anything more due to ring rust.

Ring rust

You also have to consider this as a concept. "Ring Rust" is term for Human aptitude diminishing as the result of a skill set not being applied over as set of time. If I am not continually or continuously performing a task, my ability to perform said task diminishes over time. Consider a knife. If you use a knife the blade dulls and it, therefore, needs to be sharpened. But AS you use the knife your ability to use the knife increases over time. If you stop using knife for an extended period of time, it will develop rust and dull as the natural and your ability to USE the knife will also diminish.

Hym Iam "And that's where the term 'ring rust' comes from. Aptitude diminishing as a byproduct of atrophy. What I'm dealing with now is a combination of atrophy and biomechanical disfunction. I haven't had to be serious in a while and I feel like I am fucking dying. And I could totally use your eyes. Once the Meta hud glasses improve and I aquire my own personal interface I might buy a pair."
