The instructor did a review before continuing with last night's topic Pulse Properties. Among the stuff he brought up, one point was: "if a practitioner tells you that you don't have a deep bottom pulse reading, what do you say?" What he wanted was for us to explain that it's impossible because by virtue of not being on our deathbeds, we must have a deep bottom pulse reading.
From the back of the classroom, a lady says indignantly, "CHOY!" And the entire room erupted with laughter. XD
This is a southern Chinese cultural thing. If someone says something that alludes to death, illness, accident/injury, bankrupcy, evil spirit possession or something negative like that, usually hinting at non-logical or supernatural causes, we say "choy" with a falling tone (like the Mandarin fourth tone). Either short or prolonged in voice length, it doesn't matter. It's very colloquial, so I couldn't find the exact character for it.
It's hilarious in context and especially if a quickly muttered "ai-ya" is prepended. =D
