According to Betsy Towner of the AARP October 2008 Bulletin, There are many words that kids think you don't know. They include google: searching the web especially Google, vlog: a Web log of video entries, wikidemia: a term paper that was researched entirely on http://www.wikipedia.org/ , BFF- Best friends forever, IDK- I don't know, OMG- Oh my God! ROFL- rolling on the floor laughing. TMI- too much information, sick- extremely cool, mash up- to take elements of existing pieces of music, usually of different genres, and combine them in a new song; also the resulting song.
