The phrase became a staple reaction audio on TikTok, Discord and short form edits, often shared alongside the longer oh my god bro oh hell nah man version that uses the same delivery.

Its staying power comes from how instantly readable it is, even without context, and how easily the short clip fits outros, cuts and comment style videos across platforms.
