This sound is widely associated online with the Epic Sax Guy meme, which came from SunStroke Project and Olia Tira's Eurovision 2010 performance of "Run Away." A brief sax section from that performance became a viral reaction and remix staple across YouTube, Vine, and short-form edits. People still use it because the riff is instantly recognizable and quickly signals ironic confidence, overblown drama, or a playful victory moment without needing any setup.
