|1.||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.
