back door trots 

A severe case of diarreah. This terms was used many years ago. The expression came from having to trot or run out the back door to the outhouse.

I got a case of the back door trots after eating those beans last night.

the back door trots

Discribes a person who has a severe dose of the shits.
Usually after a skinfull of beer and a dodgy curry, the unlucky person will wake up with an arse like the Japanese flag. Just a white patch with a big red dot.

Fuck me Reg, I think i've got the back door trots, I have been shitting like a pony all morning, and my arse is now on fucking fire.
