Kickup → The word is formed from "kick" (originating from Middle English *kicken*, meaning to strike with the foot) and "up" (meaning to a higher position or level). The term "kickup" refers to the action of kicking something upwards or raising it by kicking.
Think of using your foot to 'strike' ('kick') something and sending it 'up' to a higher place — that's what kickup means.
