質問: 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!
回答: They are derived from the onomatopoeia used to describe the motions the hand makes when playing. * グー comes from ぐっと, the way you clench your fist * チョキ comes from チョキン (or チョキチョキ), the sound scissors make when cutting * パー comes from ぱっと, the way you spread your hand 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 > > >
