What does "lobotomy variant" and GeometryDash variant mean?

In variants whirld, I saw things like geometry dash names and "lobotomy" names.

I like the brawl stars.

It's meme variants that originated from geometry dash. Ask @chye3mc for more information because he was the main creator of this meme.

Lobotomy is a form of brain surgery, and when brain surgery is mentioned it will refer to the lobotomy meme

no lobotomy was created by @macyip blame him lol
