The clip is associated with Dinamita Show, a well-known Chilean comedy act whose routines and catchphrases have long circulated in Spanish-speaking humour circles. As a short WhatsApp audio, calambre en el hocico travelled from chat to chat in Chile, where listeners passed it on as a ready-made reaction rather than as part of a longer sketch. Its appeal lies in the memorable, oddly specific phrase and the over-the-top delivery, which make it easy to reuse whenever someone wants a fast, recognisable joke about sudden pain or embarrassment.
