Cameroon
"You're an old pot."
This might seem like an insult, comparing a person to what sounds like garbage. However, in Cameroon, saying this phrase is a compliment to a cook. The idea is that better food is made in an older pot, one that is seasoned and weathered with use. So, if you're an old pot, it means that your cooking is delicious.
India
"Gaja Gamini"
The translation of this phrase is "She walks like an elephant." Being compared to an elephant definitely does not have the ring of a compliment. However, that is not the case in India. The idea is that someone has a slow, graceful walk and is being recognized for it. It is not, in any way, shape or form, a comment on someone's physical size. It's all about the walk.
