Hi , I'm wonder what exactly does this slang mean?

Actually, there is definition for it on wikipedia but it's little bit unambiguous...

I came across this slang in this video: 

<yt-formatted-string class="style-scope ytd-video-primary-info-renderer" style="--yt-endpoint-color:hsl(206.1, 79.3%, 52.7%);">ARE ASIANS INVISIBLE IN AMERICA OR NAH?</yt-formatted-string>

<yt-formatted-string class="style-scope ytd-video-primary-info-renderer" style="--yt-endpoint-color:hsl(206.1, 79.3%, 52.7%);">https://www.youtube.com/watch?v=nC9oG-i9CfE</yt-formatted-string>

<yt-formatted-string class="style-scope ytd-video-primary-info-renderer" style="--yt-endpoint-color:hsl(206.1, 79.3%, 52.7%);">

</yt-formatted-string>
