Help with new words

I'm sick and I'm cold. And I've put off my linguistics assignment far too long. My mind is long gone, and the only words I can come up with...are not so great. I'm supposed to find 5 new words that illustrate some type of lexical/semantic change that we've been discussing and explain the processes. And guess what words I came up with? -_-;;

(1) blog
(2) fanfic/fanfiction
(3) anime
(4) Muggle
(5) ???

Yeah. My mind's not working. Throw some new words at me? New...meaning that it first appeared no earlier than 1900.
