You're welcome.

It's a weird meme started by a YouTuber named "cs188" who makes "YouTube Poops" (which are weird jumbles of edited videos that make the people in them sound like they're saying something weird.) "The JoJ" is when a picture is mirrored on its right and left sides, where the same part of the picture that's on the left is the same part on the right.

It's also when any audio is edited to sound like it rewinded shortly after someone said something, like when someone says "Job", but right after they say it, the video is edited to roll back, so it sound like they said "JoJ". xD
