A person who eats their meals exclusively a McDonalds. They can be easily identified by the almost inhumanly oversized bodies and the ability to order breakfast lunch and dinner never having to look at the board. They are only found at McDonalds restaurants . Beware of the Mcmartians for they often become violent when their mc coffee's are messed up.
Dude cheak out all the mcmartians eating at McDonalds.
