ENGLISH EXPRESSIONS: "THE MILK"
Interestingly, the Spanish use "la leche" in a whole variety of ways and I am not going to try to translate all the different forms of "la leche" in this post because I will run out of space. Here, I will just focus on the "leche" that means "amazing/the best".
Although you could translate "la leche" as simply "the best", a better translation is an English expression: "THE BEE'S KNEES" which is quite commonly used and although sounds somewhat strange is a great way to talk about something that is outstandingly good!
Hope that helps!
