O Mati - A fake tune that plays in your head when you're doing someth

A fake tune that plays in your head when you're doing something awesome. It’s like your brain is giving you a high-five and a middle finger.

I was playing video games and O Mati came in like I was the king of the universe.

I was eating chips and my brain said, 'This is the best moment ever,' and O Mati started playing.

I was doing my hair and O Mati came in like I was about to start a new trend.
