时髦术语（英语：Buzzword，又称潮流术语、流行行话、噱头词）是通常用于管理、技术、行政、或政治等环境中的一种惯用语（idiom），也常常是新词（neologism）。潮词的使用广泛，但其真正意义经常并不明确。使用潮词的典型意图是给大众一种知识渊博的印象。「潮词」跟「行话」（jargon）的区别在于，前者意图给人印象或模糊意指，而后者在行业内有明确含义。对新技术的大肆宣传通常会使技术词汇变成潮词。潮词可能会出现在辞典中，也可能不会；但即使出现，其潮词用意也可能不同于其通常定义。

A buzzword is a word or phrase that becomes very popular for a period of time. Buzzwords often derive from technical terms yet often have much of the original technical meaning removed, being simply used to impress others, although such "buzzwords" may still have the full meaning when used in certain technical contexts. Buzzwords often originate in jargon, acronyms, or neologisms. Business speech is particularly vulnerable to buzzwords. Examples of overworked business buzzwords include synergy, vertical, dynamic, cyber and strategy; a common buzzword phrase is "think outside the box".
