喧腾 (xuān téng) is a vivid, literary verb meaning 'to surge noisily' or 'to buzz with excitement.' It combines 喧 (xuān), meaning 'noisy' or 'boisterous,' and 腾 (téng), meaning 'to surge,' 'to rise up,' or 'to surge upward'—often used for steam, flames, or crowds. Together, they evoke an image of sound and energy rising rapidly and collectively, like waves of noise swelling through a crowd or excitement bubbling up in anticipation.

This word is often used to describe lively, emotionally charged group settings: bustling markets, cheering stadiums, festive celebrations, or even natural phenomena like roaring waterfalls. It carries a positive, energetic connotation but may occasionally imply overwhelming intensity depending on context. Though it functions as a verb, it’s frequently used in descriptive phrases rather than as the main predicate, often modified by adverbs like 热烈地 or 欢快地.
