Constantipation

This is a fictional word my ten year old brother came home from school telling me his friend had informed him was an antonym for constipation. After I told him that this sounded like bollocks he said "Seriously, google 'can't stop pooing'". I did, and it turned out to be bollocks.

Along the way, however I discovered that there are several interesting synonyms for diarrhoea. These are the 'Aztec two-step' and 'Montesuma's Revenge'. Both are American slang phrases referring to the tendency of travellers going to Mexico to get diarrhoea. 'Aztec' Two-Step is just a reference to mexicans. Montesuma II was a mexican king killed by invading spaniards so the phrase's origin becomes obvious.

I never knew Mexico had such a reputation for Diarrhoea.
