Don't be confused (those who are learning english) with the 'u' in 'favourite' I use, it's the British/Proper English/Non-USA (not offense to those Americans... you're just wrong) spelling of the word.
What are your top three favourite words? In order of preference, one being the best word. They can be in spanish too, and they can be curse words.
1. Fuck.
2. Sex.
3. Music.
