I know people who use it in a similar way, essentially to acknowledge (humorously) they're using some piece of officialese, a brand name, a cliche, etc., essentially mocking the officiousness or stuffiness of it. In English, however. And mostly on their Blackberries, which can be set to insert it automatically in various circumstances.
Around here we sometimes say ™ to mark certain clichés and to distance ourselves from them. It’s practically always used in a humorous way and I think there’s a tendency to use it with oversimplifications that are often employed for promoting ideologies. For example: “You use that search engine? I thought you said it was Evil™.�? (Only in German of course.)
Is it also used that way in the English speaking world?
