jump cringe

Like a jump scare, except cringeworthy instead of scary.

When you think something (e.g. a movie or tv show) is alright until you get hit by a sudden, unexpected wave of cringe.

Also known as jumpcringe.

I was watching "The Mitchells vs. the Machines" yesterday and just when I thought the movie was getting better, they hit me with a jump cringe. Those unfunny jokes ruin the moment and give me secondhand embarrassment.
