Most people would say pvp is 2 opposite sides fighting against each other to win a battle. But if you break it down, pvp is all about annoying people whether they are in your team or not. So really if someone describes themselves as a pvper, they are basically saying they only play this game to troll people.
So what is pvp if it is just trolling?
Pvp is making yourself feel happy by knowing you have annoyed somone on the internet.Here are some examples:
Playing a healer or blood dk.
Spamming jump when fighting someone.
Refusing to buff your teamates.
Using bloodlust before the match has started.
Kiting someone the the edge of a map only to then afk out of the bg.
Trolling forums.
Picking up the flag and hiding when you are going to lose just to waste the oppostions time.
Spamming emotes.
Spamming fan of knives because it makes an annoying sound before the match has started.
Saying 'cry more' if anyone says anything in bg chat.
Playing a rogue and sapping people.
Killing someone in a bg so they have to sit and wait for a res ( rather obvious but thats why its no fun fighting bots, you know you havent annoyed anyone)
If anyone can think of some other examples of pvping, write them
