Place it at the very start of an edit as Ralf's entrance, then follow with the Bruh sound when the other characters react, and finish with Du Bist Gut Genug for a follow-up line from Ralf.
Über diesen Sound
This is a short 2.2-second voice clip in which a speaker introduces himself in German with the line 'Ich bin der Ralf.' The plain delivery turns a simple self-introduction into something funny and oddly confident, like a character stepping forward to announce himself before anything else happens. It lands as a deadpan, slightly awkward greeting that works best when the name itself is the punchline.
