Self explanatory. I've read that they stand for rock, paper and scissors, but I can't find any ultimate origin of why these terms are what they are. Thanks!


They are derived from the onomatopoeia used to describe the motions the hand makes when playing.

According to Japanese Wikipedia:

  • ぐっと拳を握るからグー
  • チョキンと切るからチョキ
  • ぱっと手を広げるからパー
