Unlike nostalgia, a longing for something good from your past and reflecting on the good old days, anti-nostalgia is when you remember something shitty from your past and being glad things are better now. The bad old days.
Jake: Bro, remember back in 2010 when we used to play Halo together on the Xbox 360? Those were the good old days, huh?

Nathan: Nah dude, I remember in 2010 when I was about to get a 20 kill streak in Reach and got the red ring of death. Had to get a new system. That shit gives me anti-nostalgia.
