As I learn English more and more, I realize English has numerous interesting metaphorical phrases like Japanese language. For example, people mean they stay late at night for studying by saying "burn the midnight oil". Metaphorical phrases using animals and fruits, veggies such as " eat like a horse", "as cool as a cucumber" and "lemon" imply that we have a completely different image towards such things. For example, in Japan, a pig is regarded as a big eater and veggies and fruits are not used as a metaphor. Instead, we use many phrases relating to our body parts. We say "Your mouth is stiff." to indirectly mean "You always keep a secret" and "My nose is crooked." to mean "It's stinky." Don't you think these phrases sound funny?
If your language has unique metaphorical phrases like these, share on this forum :)
