Spanish Word of the Day: fiera

I picked up today’s word while watching “Cómo conocí a vuestra madre” (How I met your mother, but then dubbed in Spanish). I never heard of it, and it sounds a bit weird if you ask me. So I decided to look it up in the dictionary. What’s the meaning? In English you’d translate it to “wild animal” or “beast”, but that still doesn’t say anything…

…until I looked up some examples and it’s quite colloquial! Yes, in a colloquial context it can mean “dragon” [not the mythical animal, but a person), "vicious" and "[in] rage”.
