Pneumono­ultra­microscopic­silico­volcano­coniosis 

Scientific : Pneumono­ultra­microscopic­silico­volcano­coniosis is a form of Pneumonoconiosis (hence the “pneumono” and “coniosis” parts of the word) coming from inhaled debris from volcanoes. These debris are ultra microscopic (hence the “ultramicroscopic” of the word). The inhaled debris can be ash or dust from volcanoes (hence the “silicovolcano” part of the word).

Pop culture : Longest word in English. Also very good show off on how well you can say sounds.
