Remove both the P's and you get rømt, which is Norwegian for sour cream.
Insert your own joke here about taking the Ps, it's bound to be better than what I'll come up with.
It feels like it can't possible be true, but on the other hand, I'm probably due for having my confidence in my English completely shattered again by learning another weird word's real pronunciation, so maybe this is it.
Also, I too asked ChatGPT and it told me that In the word "prompt," there are no silent P's. All the letters in "prompt" are pronounced, including the P.
