Place this clip right at the moment of introduction, then follow it immediately with a Bruh reaction from the other person in the scene. For a longer gag, let another character respond first before adding a second meme hit to close the exchange.
About this sound
This is a 1.4-second voice clip of a man delivering the line My name is Jeff in a flat, strangely serious tone. The feeling is awkward and instantly funny, because such a plain introduction lands like a punchline on its own. It comes from the comedy film 22 Jump Street, where the line became a widely repeated meme.
