Meal Friend 

A friend that one has for the sole purpose of going out to meals with. A meal friend will never be invited to go on vacations with or to any real plans. They are simply there to accompany you to a sit down meal.

I can't wait to try that new restaurant with one of my meal friends.

Friendship meal 

When a person (usually a female) accepts a dinner "date" from another person (usually a male) only to get a free meal. Often times the person paying for the meal feels like it is a real date, but really its just a friendship meal and the accepting person "only wants to be friends".

Sally accepted a friendship meal from Frank...
Poor Frank thought it was a real date, but Sally was just looking for a free meal and she only wants to be friends!

meatfriend 

Noun. A person who is considered a friend, who also exists in the real world, i.e. made of meat, as opposed to being made of bits.

Yeah, Mike's my good friend. We met on the internet, but then when I met him in person, he became my meatfriend.
