What does "mad invite" mean?

[NoName:)]

I see people using it on fb/ instagram, e.g someone posts a pic with the description "was at (place) with_____" and people comment "mad invite". Doesn't make sense to me, you can't invite someone to an outing/ event that's already happened.
Like I said, it's just pictures of people at a place or picture of food at a restaurant. There's no invitation or artwork involved. FYI I already read that answer on another question.

e.g. If you handed someone a wildly designed invitation that they thought was really cool, and they were young enough () they might respond "Mad invite!" meaning they are impressed with the artwork.

But that is all speculation - you need to give more context for your question.

It Means They Are Impressed With the Art Work As the Previous Person has Said
