Yeah, sort of. The game is Tibia, it has an item called copper shield. When I was a kid, all my friends and I used to write and pronounce it as cooper shield. I internalized that mistake to the point I actually thought the item was called cooper shield despite knowing what copper is.

So decades later I went a gaming community on the internet and suggested we all play this old game. Everything was fine until I said cooper shield. One guy immediately messaged me "br?" and I was shocked. No one else noticed it. Turns out he was also a foreigner who learned portuguese by playing the game together with brazilians and he recognized that specific brazilian mistake.
