40Karen 

A player of warhammer 40,000 (WH40K, or just 40K) who generally annoys, irritates, harasses and abuses other players over minor issues most players accept, like proxy miniatures, printed miniatures, non painted miniatures, etc.

"I was looking forward to playing 40k at my FLGS but the other player was a 40Karen who demanded i take my nightbringer proxy off my list, so i said 'fuck this' and left. He still claimed he won the battle."
