To get angry and "throw a rage" at a person(generally used in past tense). Originally developed because of a custom game of snakes and ladders (which was impossible). It was a snake taking you back to the start of the board (located in the second last square of the game). No one EVER won this game (the boards has since disappeared). The rage snake quickly evolved into a term used to describe a anger or rage (usually towards a teacher or student)
I threw a ragesnake at Misses Ioane yesterday.
Miss Cooper said i was annoying so i threw a rage snake at her.
