The term 'BUZZ or 'HISS', e.g.' is an example of ONOMATOPOEIA, which is a word that imitates a sound. ONOMATOPOEIA is derived from the Greek words 'onoma' meaning 'NAME' and 'poiein' meaning 'to make'. This type of word is used to describe a sound that is associated with a particular object or action. For example, the word 'BUZZ' is often used to describe the sound of an insect, while the phrase 'HISS, e.g.' is used to describe the sound of a snake.
