A faggoty way to say "retarded". Originated when two guys were creaming each other's throats. One of them choked, and vomited cum all over the floor. It looked like the letters "SPED". So, like the dumbasses they were, they made a term almost as stupid as them.
"I am a fucking moron. I use the term sped."
