Why do Mexicans call soups sopes and sandwiches tortas when torta means cake?

Don't be an idiot. Different languages have different words for things. 

Depending on who's speaking, torta means several things. A "turtle" is one meaning. And, indeed, the torta looks like a turtle.

Sope is a Mexican dish, made with corn meal & a red sauce. It can be describe as a sandwich.

Again, Sope can mean several things: Stinky, for one.

Meskins can't even speak their own language, much less English

Why do Americans eat burritos and call them Mexican food? 

These are just spanish words

because mexicans are cooler than you will ever be in ur entire life.

Sopa = soup

Sope = sort of a thick corn tortilla with toppings

Pastel = cake

Torta = sandwich in Mexico

Torta = cake in some Spanish speaking countries and in other languages

If you are going to be a smart-*** be properly armed.

Not sure. I know soup is sopa, but when I tried sandwich on a translator it just came out sandwich. Go figure.

The most common last name in China is Wang and it can mean a ruler or king. In some parts that is a comedy word. You can go on all day though, why is a dog called a dog? But not everywhere, it's a chen in France.
