"Doctor Muffy Siegel" in the Journal of Semantics. I loathe the rapidfire occurrences of "like" in teenspeak, especially when I hear my contemporaries (geezers) using it. After listening to the clip, I understand how it may be useful (if not warranted) at times but, after "Muffy" the linguist purported to justify the use of "like," I do wish the interviewer would have asked her what people said instead of and prior to the invasion of "like."
Like, thanks for the link.
Ummm.... They said ...ummm... something else. You know?
Like gag me with a spoon!
