I was OK when my brother used the term “Bizzzorred” to say via IM that he was bored.  I even accept LOL and ROFL and anything we used in middle school to keep an AIM conversation going.  But one term that stretches my knowledge of ever-evolving elite-speak and Internet slang, and doesn’t even appear in UrbanDictionary.com as far as I can tell, is “^H^H^H^H”

For a few years I’ve seen “^H” probably only on SlashDot but seemingly in different ways.  Most recently it was part of a response on an article about The Nintendo Revolution controller. 

“Surely Mario is Missing and Zelda: Wand of Gamelon are ideal ports to the CD-I^H^H^H^H Revolution?”

I’ve replied to the comment as an Anonymous Coward asking the poster what the term means.  Anyone know?  What other mysterious Internet-speak do you want defined?

Update: Thanks to the 1337 Arden for solving the mystery and providing the Wikipedia link on Backspaces.  Each ^H, or Control-H, is a backspace.  So the poster on SlashDot was writing out “CD-I” and jokingly taking it back.
