That isn't a good test either. I know that most SEOs do those kind of tests.

But the fact is, Google tries to show its users at-least one relevant result for their search queries. If that gibberish word is found in the source code of any html page, irrespective of whether it is defined within a meta keyword or not, Google might still return that page as the most relevant result for the query.It however doesn't mean that meta keyword tag is always used by them.
