Place it near the end of a short montage about crowded seats and lost personal space, after the visual gag is clear. Follow it with a Bruh reaction for the next beat, then an Oh My God moment to close the scene on a bigger laugh.
このサウンドについて
This is a short spoken clip, about two and a half seconds long, in which a voice delivers the line 'Hey, I'm spreading my legs' in a casual, drawn-out way. The delivery makes it feel awkward and cheeky rather than serious, like a deliberately uncomfortable joke dropped into a conversation. It works as a quick, suggestive punchline that catches listeners off guard and makes them laugh at the bluntness.
