Well, I'd say that on message boards and such, 'golf clap' or 'slow clap' somehow has come to have a less sarcastic meaning, in my experience, as it does in the film.
Off-topic, but as a writer and grammarian, it reminds me of how the original meaning of 'nonplussed,' which is puzzled, has sort of given way to people using it in a different way simply because of the two parts of the word. People apparently are thinking 'nonplussed' should mean 'not moved,' 'not perturbed.' I guess sometimes words and memes take on a life of their own in this internet age.
And don't get me started on the many sportscasters who have combined 'intricate' and 'integral' into a made-up word pronounced as 'intrical.'
Anyway, getting back to the topic, I can't stand the outfit!
