ASSMONKEY
Above you will see a rendition, as depicted by South Park, of a 4 assed monkey. What possible use could there be for a monkey to have 4 asses, you might ask? Absolutely no use whatsoever. I am using this to demonstrate the uselessness of certain people. When someone is referred to as an "assmonkey", you will now have a visual reference to call upon, and you will be able to equate "assmonkey" with "useless person".
But then again, make any reference you want to. What do I care. Ya bunch of assmonkies.
