Spite Monkey
A Spite Monkey is a type of volunteer editor working for Urban Dictionary who, having had a definition rejected, goes into a session to approve new words and rejects anything and everything irrespective of its value. A childish, nasty, little fuckwit whose actions hold back progress and discourage others from contributing. They don't bother looking to see how their definition can be fixed, they just throw all of their toys out of the pram and reject everyone else's definitions.
"I've had four sound definitions rejected by Urban Dictionary, I'm not sure why."
" Don't worry about it, it's probably just some American spite monkey who doesn't understand English!"
