  • Digger (Chris Mulligan) - the use of grass and "to grass" in this way arose as street argot in the London criminal subculture and dates back to the early part of the 20th century.

    There are two popular theories about how this came about - one is that it derived from the expression snake in the grass which actually dates all the way back to the Roman writer Virgil. A more likely possibility, since the usage first arose in London, is that it is rhyming slang for to shop or shopper, which have similar meanings (to shop someone is to turn them in to the police).Follow, if you can, the twisted route through rhyming slang - Policemen are often called "coppers" in British slang. That becomes "grasshoppers" in London slang. Someone who turns his pals, or their information over to the police "shops" them to the authorities becoming a "grass shopper", simplified to "a grass". Maybe that's where the word comes from and maybe its origins will remain shrouded in mystery.
