I was just watching a video where someone dropped food and said “3 second rule right?” In english with this subtitle 3 秒ルール" Does anyone know if this phrase actually used in japanese? and if so is it 3 second? In Canada we always said 5 second rule.
さんびょうルール / ごびょうルール
Someone asked me once if we have the 3-second rule in America, and when I told them it was 5 they looked at me like I was crazy. It could entirely depend on region/family, which I’d imagine goes for Western countries as well.
