Back in approx. 1965 I originated the term Crudhopper. It was in Ottawa and I was in high school. It spread throughout Ottawa, Canada, the USA and god knows where else! I moved on to bigger and brighter things ... like girls!
Definition: The original term was used to describe someone who had the ability to circumvent rules and regulations, but then alas became a rather derogatory term for people.
He's such a Crudhopper, he took his own locker and put a lock on it!
That Crudhopper handed in a paper that was done by his sister tens years ago.
