Ha! My father used to say PERKELE all the time when he was pissed!
Brings back memories.
It’s pretty much standard operational procedure for a Finnish male.
Perkele is probably the first word you need to learn if you want to learn Finnish. It works for any occasion. If you get a new PR, its great. If you need to encourage someone, it works very well. If someone misses a lift, it works exceedingly well. You can order a beer with it. You can get a telemarketer to stop talking with it. I don’t think there is an occasion it doesn’t work for. I’m sure one could even use it for dirty talking. At least if the sex is aggressive enough.
