I’ve never heard of ricing but come to think of it I have heard of “rice rocket” to describe Kawasaki motor bikes so that’s probably a titch racist.

Of interest, in Canada’s 2011 federal election the Conservative party with Stephen Harper won by painting Michael Ignatieff as a book nerd professor from Harvard University.

They ran ads with taglines such as “Just visiting,” “Just in it for himself,” and, most notoriously, “He Didn’t Come Back For You.” These all suggested he was an erudite professor from the USA who wanted to run Canada for his own self-aggrandizement and mocked his intelligence and academic bona fides.
