Is another name for the anal region. Used in place of actually using the word rectum. Has been used quite recently by stand up comedians in the surrounding Houston area.

Not sure where the word cline originated but most people when asked assume it has something to do with the word incline. They just say it with the understanding of what it stands for. And now you know.

I ate the tacos on Thursday and by 10:00am I was blowing out the clone hole.
