Some french expressions that I illustrate!
Un vent à décorner les boeufs. (when there is too much wind, we say that it could dehorn a beef)
Il pleut comme vache qui pisse. (when there is too much rain we say that cows are pissing)
Envoyer du steak. (litteraly it means "to send a steak", but in fact we use it when someone is full of energy)
Ca sent le sapin. (litteraly "it smells fir" which means that there is a smell of death)
