Though the word sounds like "Hashish", it is derived from the Japanese number "hachi" which stands for the number "8" in English. The word hachis is generally used by street racers (with little or no knowledge about JDM vehicles) to refer to the famous Toyota Corolla AE-86. A true JDM enthusiast or a real owner of an AE86 would refer to the car as "hachi roku" which means 86, and not just hachis. The Corollas that were produced from 1983 to 1987 and came with 4A-GE engine (+other options) were called AE86 or Hachi Roku.
Mr.Jackass- "I wanna buy a car that drifts well and im thinking of gettin one of those hachis"
Mr.JDM- "Its not hachis you idiot, they are called Hachi Roku. Before you talk about drifting atleast try to name the car right coz an AE86 is a well respected car in the drift world"
Mr.Jackass- "Sorry man.. I heard that name from some wannabe street racers"
