Just like a Grammar Nazi, but with quotes. Mostly shows his/her head at partys or forums. Generally joining in on a conversation to correct every quote that is even the slightest bit of.
Dude 1: "I love the knight who say ni scene in monthy python!"
Dude 2: "Yeah!! "You shall cut down the biggest tree in the forest with a HERRING!!"
Dude 3:"You got it all wrong, it's mightiest! Not biggest! "
Dude 1:"Man, you're such a quote nazi!"
Dude 1: "And then the toast king says:"Looks like the left to me!""
Dude 2: "Haha! I love that part!"
Girl: "You forget more. He says that it looks more like the left to him. Get your quotes right!"
Dude 2: "Oh-oh! We got ourselves a quote nazi here!"
Dude 1: "I hate you"
