Diarrhea Diwali

Recently I have, unfortunately, been a victim of explosive diarrhea. Whatever, it's India, that happens. I had the following Hindlish conversation with my Hindi teacher:

Teacher: आपकी तबीयत कैसी है? / How is your health?

Me: आज... बहुत अच्छी नहीं | / Today... not so good.

Teacher: क्यों? क्या हुआ? / Why? What happened?

Me: हिन्दी में "explosive diarrhea" का मतलब क्या हैं? / What is the meaning of "explosive diarrhea" in Hindi?

Teacher: हम "explosive diarrhea" नहीं कहते हैं | Diarrhea का मतलब "दस्त" है | / We don't say "explosive diarrhea." The meaning of diarrhea is "dast."

Me: लेकिन मैं "explosive" कहना चाहती हूँ | यह साधारण दस्त नहीं था | / But I want to say explosive. This was no ordinary diarrhea.*

Teacher: ठीक है | आप "ब्लास्ट" कह सकती हैं | / Ok, you can say "blast."

Me: दस्त का ब्लास्ट? / Diarrhea blast?

Teacher, laughing: हाँ जी | तो क्या आपने दवा ली? / Yes ji. So did you take medicine? ("take medicine" = "davaa li")

Me: Diwali? DIARRHEA DIWALI?! BAHAHAHAHAHA

Teacher, laughing: I was asking if you took medicine.

Me: OOOHH, DAVAA LI!! BAHAHAHAHA

Teacher: आपको कभी कभी ज़्यादा ध्यान देनी की ज़रूरत है | / You need to pay more attention sometimes.

Me, still doubled over in laughter: माफ़ कीजिये | दस्त के ब्लास्ट मेरे मन में थे | ब्लास्ट | दिवाली | समझ गए? समझ गए?! / I'm sorry. Diarrhea blasts were on my mind. Blasts. Diwali. Get it? Get it?!

Teacher: समझ गया | It was Diwali in your toilet. / I get it. It was Diwali in your toilet.

Me: YES. YES IT WAS.

Further research has revealed to me that "explosive" in Hindi is विस्फोटक, "visphotak." So explosive diarrhea would be "visphotak dast." But I kinda prefer the ring of "dast ka blaast." Either way, these are not not the most useful phrases I've ever learned in Hindi.

*Explosive diarrhea is, arguably, ordinary diarrhea in India.
