Am I the only one.....

Who feels like an idiot saying pvp'er? (Player vs playerer) the term in every other game I've played is pk'er or player killer but noone knows what it means so I'm stuck with this term. Everyone should just start saying pk'er

No. The term PvPer isn't wrong. A verb is a doing word, i.e. to PvP or to play are verbs. Adding an -er suffix to a root verb makes in a noun, i.e. a PvPer or player.
