Misalgia 

The feeling of sentimental distaste for the past, typically for a period or place with negative personal associations.

Listening to Crazy Frog gives me the strongest feeling of misalgia, I used to hate it! Wanna go listen to some of their songs?

That one best friend everyone needs in their life. Reminds you to take a break. Takes care of your every mood. Motivates you to keep going. Stays close to your heart. It's hotter than your ex.

"A breakfast isn't breakfast without Misalgram's Misal."
"Damn that person is such a Misalgram!"
