Horizontal stalactite 

Is the build up of semen on the rear divider of a desk. Overtime the dried semen forms a stalactite on the horizontal plane.

What is that under your desk Jimmy?
Oh that's just my horizontal stalactite Mum.

horizontal shit 

A shit that is horizontal.

A horizontal shit is essentially a turd that turned sideways while still inside the rectum, forcing it to come out horizontally, often rupturing the anus in the process. It often occurs when one has to keep themselves from defecating for extended periods of time.

"damn man, yesterday I had a horizontal shit so bad it made my ass look like the Japanese flag"
