40th hour dump 

When you're nearing the end of your work week, still on the clock, and you spend your last precious moments productively seated on a toilet letting your excretory system gets some exercise. A foolproof method to greeting the weekend, now that you've made your money and gone on one final business trip to the bathroom.

"We all begrudgingly attended the 4pm meeting on Friday, that is except for Jared. He had to meet with the toilet for a 40th hour dump."

40th base 

Two trains on the same track are moving towards each other, each at a speed of 40 miles per hour. On the top of one train stand 50 naked guys with boners. On the other train stand 50 naked girls who are horny. What happens to the ones that don't fall off when the two trains run into each other is called 40th base.

Damn, i just got an orgasm from 40th base....it sure was pleasureful...

40th 

Noun - A Unit of Time = 1 hour in a 40 hour work week (ie. 1/40)

You begin work at 8am on a Monday morning. At 9am a co-worker looks ("prairie-dogs") over the cubicle wall and suggests getting a cup of coffee. The co-worker then states "How's it going?" and you reply "Great. Only 39/40ths until the week is over."
