PVP - Explain it to me !

Hi guys.

I'm a pure PVE player. I did some wild pvp and battlegrounds with my hunter few years ago but I've never really seriously tried to be PVP player (arena and stuff).

SO TELL ME, BAD ASS PVP PLAYER ! TODAY : What it's like ? What do you do ? What's to know if someday I want to do real PVP ? What makes a PVP player a kicking butt machine ? Do you also do PVE ? Are you raiding ? What class is PVP material ? Why are you so mean with pve players ? What's your favourite color ? Do you level up your professions ? Do you have PVP addon ? Do you think raiding is more or less difficult ? Do you hate mage ? (caus I do), Why do you always yell on the chat ? Do you care about frags ? What is the best title to show as PVP players ? What are your customs and habits ?
