「flex」主要指關節彎曲或肌肉收縮；「stretch」則指拉長或伸展肌肉、肢體，使其變長或變緊。
flex vs show off
在俚語中，「flex」指炫耀（財富、能力、成就），語氣較新潮、直接；「show off」是更通用、歷史更久的「炫耀」用詞，可能帶有負面批評意味。
在對話中，人們有時會用「flex」來引述或模仿他人炫耀的行為，語氣常帶有調侃或諷刺。 EN: He was like, "Check out my new car," just trying to flex. 翻譯: 他那時就說：「看看我的新車」，根本只是想炫耀。

正式寫作注意：在正式報告、學術論文或商業文件中，應避免使用「flex」的這種俚語含義。請改用「show off」、「boast」、「demonstrate (one's ability/strength)」或「highlight (an achievement)」等更正式、語義明確的詞彙。
