Nonchstalgic 

A mix between nonchalant and nostalgic.
To be nonchstalgic is to feel nostalgic but not really caring about the exact moment you’re nostalgic about.
It’s like floating on memories without attaching importance to them.

I was scrolling through old photos yesterday… I wasn’t sad or happy, just nonchstalgic.

Noncestalgic 

In the face of Operation Yewtree and other similar investigations, many 70's, 80's and 90's childhood memories are tainted by the presences of nonces and sex offenders such as Jimmy Savile and Gary Glitter. Thus, instead of being nostalgic for Top of the Pops hosted by Jimmy Savile, you're noncestalgic.

Person A: I'm so noncestalgic for Gary Glitter's music.
