Most commonly found in the Northeastern section of the United States where pronouncing the letter "R" is optional in most cases, "On Mars" or as it is commonly said "on Mahs" is a term to describe incredible hunger. The New Englander will often say "I'm starvin' like Marvin the Martian".

"Marvin the Martian" is of course a reference to the Looney Toon character.

As you can imagine, this quickly develops into somebody asking "What are you, on Mars?"

So, to cut out the middle man, one can simply declare their state of hunger by declaring that they are "ON MAHS" and need to eat immediately.
-"Guy, I'm on Mars"

-"Me too man, we should Ring the Bell

(Ringing the Bell refers to eating a Taco Bell, but that is a different story).
