Place this clip right after the failed impression in your edit, then follow it with the Bruh Soundboard Button for the reaction, or swap that follow-up for the Emotional Damage Sound Button when the roast needs a bigger finish.
About this sound
This is a very short vocal clip of Lydia making a loud noise as she tries to imitate Delzao and gets it completely wrong. The attempt collapses almost immediately, which makes it feel awkward, silly and instantly funny, like watching a confident impression fall apart in front of everyone listening in that moment.
