Toasting (rap in other parts of the Anglo Caribbean), or deejaying is the act of talking or chanting, usually in a monotone melody, over a rhythm or beat by a reggae deejay. It can either be improvised or pre-written. Osbourne Ruddock (a.k.a. King Tubby) was a Jamaican sound recording engineer who created vocal-less rhythm backing tracks that were used by DJs doing toasting by creating one-off vinyl discs (also known as dub plates) of songs without the vocals and adding echo and sound effects.
