A person who has been using steroids for a long time and consequently has smaller testes and a short fuse. Generally on some competitive team or another, you see this type slavishly adoring the man with the biggest pecs at the local GNC store or muscle gym. Generally displays clouded thought processes, is quick to anger, and has trouble expressing himself eloquently (all known examples are male). Known to beat family members or significant others. Should be considered armed and dangerous.
"That's not a strategically shaved chimp flinging poo, that's a Roid Monkey....flinging poo."
Something that is so utterly absurd..it even qualifies for sheer stupidity and making an ass of someone or something. A mix between Ridiculous and Assinine (sp?) Can also be used as an exclamation for something funny or sarcastic. (depends on the inflection of voice and situation)
"I cannot believe what he said in that meeting...that's just Ridonkeyoulus (re-donke-you-lus)!"
OR
"That video was friggin Ridonkeyoulus (re-donke-you-lus)!"
Scott: Batista, Ultimate Warrior, Hulk Hogan, Scott Steiner, and Superstar Billy Graham are all examples of roid monkeys (Graham is a self-admitted one)
