"Ano" was weird for Spanish speakers and now there's "bunda" for Portuguese speakers :D
Always makes me laugh. Bunda is a type of fur coat in Serbian, but since I've been talking to a lot of Brazilians, I can never not hear the Portuguese meaning ;)
Our Brazilian "bunda" came from an African language. I am wondering what is the origin of this word in Czech...
Bunda comes from Hungarian https://en.wiktionary.org/wiki/bunda#Hungarian.
