From urban dictionary:
A website full of cynics who yearn for the approval of those around them, and anonymously harrass people online for not conforming to their community’s beliefs, which they themselves have religiously adopted. Boy ol’ gosh golly, I sure do love going onto Kiwi Farms and laughing at autists and liberals!
