the audio is from a fansign, and OP asks if he remembers the sign he laughed at when they came back from Jakarta (shown in the video) which said "Maybach (a Mercedes-Benz) don't get hurt!!"
and he said it just made him laugh really hard because it's a meme he/zb1 uses a lot!!

Taerae specifically has used it with Gunwook before, a few months ago when Gunwook was sick Taerae would go around saying "My Ferrari got a scratch, what should I do?!" lol. It's a joke that comes from fans to begin with (not just zb1, fans in general) so it's extra cute and funny how much Taerae likes it
