Flexi-shit 

Time taken by a person on flexible working hours, at the end of the day, to use the bathroom before going home, thus allowing them to add their toilet time to their Time Sheet as if they were actually working for that extra ten minutes.

Easy way to get additional holiday without actually doing additional work.

6 flexi-shits = 1 hours lie-in one morning.
45 flexi-shits = 1 days flexi leave.

Counting my flexi-shit this evening, I can now have a half day holiday on Friday, yay!

Flex Shit 

That sticky poop that seals itself to the back of the toilet and no matter how many times you flush it... it won’t go away. It is the Flex Seal of feces.

“Dude, I just took this nasty “Flex Shit” that just won’t go away. I swear it could be used to seal Phil Swift’s glass boat.”

To like something so much that you use or eat it all the time.
