When excrement blocks the bathroom toilet.

There was a serious log clog for which I needed a plumber asap!

One Log Clog

When you take such a massive shit that it only takes one log to clog the toilet...

Person 1: Man, I ate way too much at Golden Corral 's Endless Buffet ™. When I got home I was about to blow. The shit was so massive that it was a one log clog.
Person 2: What the hell is a one log clog?
Person 1: It's when one continuous stream of shit is enough to clog the toilet...

Clog Log

A massive deuce birthed with the sole intention of ruining a janitor or plumber’s day.

Tim: How were the bathrooms?
Horace: I dropped the biggest clog log of my life in the shitter.
Tim: Making a big impression, I see.

Log Clogger 

(1) Fecal excrement of such abnormally large girth that it is (or would be) unable to be eliminated by the flushing mechanism.

(2) Large bowel movement that overwhelms the capabilities of modern plumbing. May or may not be the size of the hole in the toilet.

Michelle dropped the old log clogger at Sarah's apartment and she had to have her septic system reinstalled

You call that a log clogger man? I have thicker dumps that that after a week of eating split pea soup.
