Popular culture references such as TPM's "muy bad" (mispronounced from the original) have entered common speech, often without conscious recognition of the source of the reference (and, ironically, often among those who truly hated Jar Jar). (In passing: how much of the fervour over TPM had to do directly with the gradual/possible transition of SW from popular culture to high culture?)
The interesting trend I have been noticing of late is an increasing tendency to say out loud what is usually considered Internet language. One hears "lol" (really!) and other short forms spoken among teenagers who do not frequent the Internet. Just three days ago I saw <grin> printed in a theatre's brochures and posters: not the first time I have seen these references in non-electronic print, but perhaps the most "haut culture" adaptation to date.
Are the forms developed for Internet language becoming a part of regular speech and non-Internet writing?
