Its about the meaning of "Mellorine~~!" whenever we come across lovestruck-Sanji. So, what exactly does "mellorine" mean? In the way that Sanji says it?
So far all I've found is a a Wikipedia entry that states…
Mellorine is a non-dairy alternative to ice cream, with vegetable fat subsitituted for milk fat.
…and I don't think that Sanji uses the word exactly in that context XD!
