Are you talking about the way young people use the word these days? I'm thinking it was probably about the same time people started talking and writing (places other than text messages) in text-ese.

: Drives me bananas. Makes ya look IGNORANT!
And on a side note, what is with the young people putting a boatload of excess letters in their text messages/FB posts, whatever? As in: So borrrreeeeed, texxxxxt meeeeeeeee? Goiiiiiinng to my babieeeeeeeesss, texxxt meeeeeee. Umm, yeah okay. You need surgeryyyyyy to removeeeeee excess voweeeeeeels. You gotta say "ur" instead of you're, but you're going to stick ten extra letters in your other words?

Bizarre. I completely skip over my niece's FB posts because it annoys me too much to weed out the 50 extra letters to figure out what a one sentence post is supposed to say.
Sorry for the sidetrack.
