"All your commas are belong to Array" and similar — is this grammar form "proper"?

I've often come across "weird" sentences like, say, instead of:

All of your commas belong to Array.

It writes:

All your commas are belong to Array.

It's not just once or twice, I actually see it all the time.

Is this usage actually grammatical or is simply a joke grammar?

Solution 1:

This is a variation on / reference to the "All your base are belong to us" meme.

"All your base are belong to us" [...] is a broken English phrase that became an Internet phenomenon or meme in 2000–2002. [...] The text comes from the opening cutscene of [...] the video game Zero Wing, which was poorly translated from Japanese.
