I could be wrong, but I belive hokus pokus board translates from "crazed old dude" speak as skateboard
hokus pokus coming from the latin word herk polk meaning magic ways and skateboard coming from punk meaning board with wheels
old dudes get confused when they see a olly so they tend to think that the board is magic
"You damn kids, get off my proporty with them there hokus pokus boards! this heres private popertie!" no its not u stupid old hag its a sidewalk which is owned by the city
