a loose tongue, or: he couldn’t keep his mouth shut

M just called me from Davao (where he’s studying Cebuano, the main language of the Visayas region of the Philippines, as well as northern Mindanao) to tell me he has diarrhea. Admittedly, the diarrhea was an incidental point. Given his condition, he’d looked up the word in his Cebuano-English dictionary and decided – rightly – that the definition therein had to be shared. It's a doozy even without the knockout punch at the end (bear in mind that some Filipinos mix up their Bs and Vs).

Diarrhea (n): pagkalibanga
Morbidly persistent purging or looseness of the vowels.
