When you have a brain fart but it's much more severe. The longest of which was called Brexit
"Damn Teresa may had a Matthew moment when she declared brexit."
When someone does some dumb shit. Commonly used in reaction to someone else’s dumbfuckery, or in response to an image “Matthew” would make.
Wow. That was one hell of a Matthew Moment
When something silly happens to someone or something that causes a group laughter.
We laughed at the man falling, he had a Matthew moment.
