Plebey plebes plebing plebilly
HP fandom has many terms. One of them is "plebe." As you can see from this thread, the definition is quite flexible. Basically, the term can apply to anyone, from someone with poor spelling and grammar to someone with good spelling and grammar that happens to disagree with you.

The use of the term "plebe" in HP fandom is a HOT!HOT!HOT! topic! This thread barely lasted 3 days!

I thought you all might like some of the wanktastic posts to this thread. Intellectual puffery is always amusing to see, especially when it relates to a fandom term.

P.S. Yes, I did post in the thread, feel free to wank on me! I need to remember that Fandom is fucking funny!

P.P.S. There's even a few mentions of Fandom_Wank!

[edited to add] I personally do not use the term "plebe," cause I think the whole idea of labeling someone in an insulting manner for being "stupid" based on message board posts is wanky to begin with.
