Sim Sim Salabim origionated from the little guy with a turban from the T.V. series Jonny Quest.
Its technically jibberish but im pushing for it to be defined as meaning madness.
"Sim Sim Sala Bim" are the magic words said by Hadji on the shows The Adventures of Jonny Quest and The Real Adventures of Jonny Quest. He used these words, akin to "Abra Cadabra" and the like, to perform such feats as hypnotizing bad guys, removing the bullets from an enemy's gun, levitating objects, and opening locked doors. However bergies from Cape Town use it as a derogatory phrase
