Space Comma is a satirical taunt demonstrating the poor use of grammar that flat Earth believers frequently use on comment threads on internet message boards.

It has become a very well known joke among the community and is used when quoting a flat Earther who has typed a space before a comma punctuation mark.
"Show me the curve Space Comma oh you can't Space Comma so the Earth is obviously flat."
