One sandwich short of a picnic:腦袋少根筋,愚笨
One sandwich short of a picnic:意思是腦袋少根筋,愚笨.筆者也見過'two sandwiches short of a picnic'的說法,但意思都一樣.Generally used when telling someone they are really stupid.
類似'an X short of a Y'這樣的短語還有很多,都是同樣的意思,例如還可以說成one brick short of a load,a few fish short of a hatstand等等.
After talking to him for about 10 minutes I decided he was definitely one sandwich short of a picnic. 我和他談了10分鐘話,覺得他很笨(腦袋缺根筋).
You really are one sandwich short of a picnic aren't you! 你弱智啊?(慎用)
