(noun) A wild, often rabid motorcycle rider. IronDingo's are very rarely found in captivity and are known to prey on Eco-conscious retards that drive hybrid cages. While most scientists agree that they are an endangered species, IronDingos are more likely to found on the FBI's most wanted list than the EPA's protected species list. It is theorized that this is due to the IronDingo's uncanny ability to ride headlong into speed traps, saloons and wayward trees.
